A display utilizing cholesterin liquid crystal polymer for enhancing contrast
includes
a transparent substrate on which a bus-bar, an electric hole conductive layer,
a lighting layer, an electronic conductive layer and a cathode electrode layer
are sequentially overlaid. An insulating packaging layer is disposed on the cathode
electrode layer. The electric hole conductive layer is painted with polymer electric
hole conductive material and coordinated on the bus-bar. The lighting layer has
cholesterin liquid crystal phase and is made on the coordinated electric hole conductive
layer. The lighting layer goes 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 is attached to
one face of the substrate.
