DETAILED DESCRIPTION OF THE INVENTION

The present invention now will be described more fully hereinafter with reference to the accompanying drawings, in which embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. In the drawings, the thickness of layers and regions are exaggerated for clarity. Like reference numerals refer to similar or identical elements throughout. It will be understood that when an element such as a layer, region or substrate is referred to as being “on” or “onto” another element, it can be directly on the other element or intervening elements may also be present.

It will be understood that, although the terms first, second, etc., may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another region, layer or section. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the present invention.

Spatially relative terms, such as “beneath”, “lower”, “upper” and the like, may be used herein for ease of description to describe the relationship of one element or feature to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation, in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the exemplary term “beneath” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

Embodiments of the invention are described herein with reference to cross-section illustrations that are schematic illustrations of idealized embodiments (and intermediate structures) of the invention. As such, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and/or tolerances, are to be expected. Thus, embodiments of the invention should not be construed as limited to the particular shapes of regions illustrated herein but are to include deviations in shapes that result, for example, from manufacturing.

The light generation unit, the light guide plate 10, the reflection plate 20, the optical sheet member 30, the display panel 40, and the upper mold 50 may be received in the receiving space.

In an exemplary embodiment, a combination portion 122 and a chassis support portion 124 may be formed on an outer side face of the receiving side portion 120. The combination portion 122 may configured to be combined with the top chassis 150 by using elasticity, where portions of the combination portion 122, the chassis support portion 124, and the top chassis 150 are configured to deform under an applied force and then return substantially to their original positions when the force is removed. The chassis support portion 124 may be configured to support the top chassis 150.

In an exemplary embodiment as illustrated in FIG. 2, the combination portion 122 and the chassis support portion 124 may be formed on one side face of the receiving side portion 120. In another exemplary embodiment, a plurality of combination portions 122 and chassis support portions 124 may be formed on a side face of the receiving side portion 120. Alternatively, the combination portions 122 and the chassis support portions 124 may be formed on all of the side faces of the receiving side portion 120.

In an exemplary embodiment, the combination portion 122 may include a combination body 122 a and a combination head 122 b. The combination body 122 amay have an elongated shape. The combination head 122 b may be combined with an end portion of the combination body 122 a. The combination body 122 a may extend in an outward direction from the receiving side portion 120 and/or be integrally formed with the receiving side portion 120. In another exemplary embodiment, the combination head 122 b may include synthetic resins having spaces therein so that the combination head 122 b may have elastic portion enabling the combination head 122 bto be moved a predetermined amount by an external force and return substantially to its original position when the force is removed. In another exemplary embodiment, an edge portion of the combination head 122 b may be combined with the top chassis 150 so that movement of the top chassis 150 with respect to the bottom mold 100 may be substantially limited.

In an exemplary embodiment, a portion of the chassis support portion 124 may extend from the receiving side portion 120 and/or be integrally formed with the receiving side portion 120. In an exemplary embodiment, the chassis support portions 124 may be slanted or extend at an angle with respect to the receiving side portion 120. Additionally, the chassis support portions 124 may be configured to push the top chassis 150 in a direction away from the bottom mold 100 so that the top chassis 150 may be firmly fixed with respect to the bottom mold 100. Alternatively, the chassis support portion 124 may be configured as a spring having elasticity.

In an exemplary embodiment, the top chassis 150 may be combined with the bottom mold 100 so that the top chassis 150 may prevent or substantially reduce the display panel 40 from being damaged by external impacts or vibrations. In addition, the top chassis 150 may be configured to substantially limit movement of the display panel 40 with respect to the bottom mold 100.

In an exemplary embodiment, the top chassis 150 may include a panel support portion 152 and a chassis side portion 154. The panel support portion 152 may be substantially parallel with the receiving bottom portion 110. The chassis side portion 154 may extend from an edge of the panel support portion 152. The chassis side portion 154 may be substantially perpendicular to the panel support portion 152.

In an exemplary embodiment, the panel support portion 152 may selectively cover an edge portion of the display panel 40 so that the panel support portion 152 has an opening exposing a central portion of the display panel 40 therethrough. The panel support portion 152 may be configured to apply pressure to the edge portion of the display panel 40 so that the display panel 40 may be fixed to the bottom mold 100. The display panel 40 may display images through the opening of the panel support portion 152.

In an exemplary embodiment, the chassis side portion 154 may include a combination hole 154 a. The combination hole 154 a may be combined with the combination portion 122. Because the combination hole 154 a is combined with the combination portion 122, the top chassis 150 may be combined with the bottom mold 150. The combination head 122 b may be configured to include an elastic portion. Thus, at least a portion of the combination head 122 b may be elastically bent so that the combination head 122 b may be inserted into the combination hole 154 a, and thereby combined with the combination hole 154 a. Thus, the combination head 122 b and the chassis support portion 124 together may enable the top chassis 150 to be firmly combined with the bottom mold 100.

In an exemplary embodiment, the combination head 122 b may be configured to apply pressure to the chassis side portion 154 in a direction toward the bottom mold 100. In an alternative embodiment, the chassis support portion 124 may be configured to apply pressure to the chassis side portion 154 in a direction away from the bottom mold 100. Thus, the top chassis 150 may be firmly combined with the bottom mold 100.

In an exemplary embodiment, the display device includes an edge-typed backlight assembly (not shown) where the light generation unit is positioned on a side face of the light guide plate 10. In an alternative exemplary embodiment, the display device may include a direct-typed backlight assembly of which the light generation unit is positioned beneath the display panel 40 to directly supply a light to the display panel 40.

As illustrated in FIG. 2, the display device may include the reflection plate 20. Alternatively, the display device may include a metal reflection layer instead of the reflection plate. The metal reflection layer may be positioned on the receiving bottom portion 110.

In an exemplary embodiment, as illustrated in FIG. 2, the display device may include the bottom mold 50 formed by an injection molding process. Further, exemplary embodiments of the display device include configurations where the bottom mold 50 may be formed from a metal or plastic.
