Abstract

A liquid crystal module comprising a liquid crystal layer containing a plurality of pixels therein, a waveguide layer, and a reflective layer provided between the liquid crystal layer and the waveguide layer, the reflective layer includes a plurality of reflective areas and a plurality of apertures to permit light to pass therethrough. The waveguide layer can include a transparent material having first and second surfaces and a plurality of spaced-apart waveguide structures defining apertures therebetween disposed within the transparent material. The waveguide structures can be configured to guide light, entering the first surface of the transparent material, through the film and permit such light to exit the second surface of the transparent material.
