Patent ID: 6917398

Claim:
A display utilizing cholesterin liquid crystal polymer for enhancing contrast, the display comprising a transparent substrate and a transparent bus-bar overlaid on the substrate, an electric hole conductive layer being overlaid on the bus-bar, at least one lighting layer being overlaid on the electric hole conductive layer, an electronic conductive layer being overlaid on the lighting layer, a cathode electrode layer being overlaid on the electronic conductive layer, an insulating packaging layer being disposed on the cathode electrode layer, the electric hole conductive layer being painted with polymer electric hole conductive material and coordinated on the bus-bar, the lighting layer having cholesterin liquid crystal phase and being made on the coordinated electric hole conductive layer, the lighting layer going through backfire to be arranged into such a structure that the cholesterin liquid crystal lighting molecules can induce and emit manual circular polarized light, a circular polarizing optical coating being attached to one face of the substrate.
