  1. The ornamental design for an illuminating apparatus for liquid crystal display device, as shown and described.

The article according to the design is incorporated in a portable telephone, a portable terminal for information device, etc. so as to illuminate a liquid crystal display from the front side.

Light emitted from the light source, traveling through a light conductive member and a light diffusing plate and introduced into a light conductive plate uniformly illuminates the whole surface of the liquid crystal display thanks to micro-prisms formed on the surface of the light conductive plate.

A transparent cover is provided over the exposed surface of the article incorporated in the portable telephone, etc. so as to protect the micro-prisms from dust, dirt, scratches, etc.

FIG. 1 is a front view of an illuminating apparatus for liquid crystal display device showing our new design;

FIG. 2 is a top plan view thereof;

FIG. 3 is a bottom view thereof;

FIG. 4 is a left side view thereof;

FIG. 5 is a right side view thereof;

FIG. 6 is a rear thereof;

FIG. 7 is a cross-sectional view taken along the line 77 of FIG. 1;

FIG. 8 is a cross-sectional view taken along the line 88 of FIG. 1; and,

FIG. 9 is an enlarged view of the portions 9 and 9 of FIG. 7.

A light source (i.e., light emitting diode) for illumination is disposed inside a housing frame which is shown at the lower side of FIG. 1.

Two flexible printed circuit boards extending downwardly in FIG. 1 are connected to a power source.
