ABSTRACT:
A bright and large information capacity projection-type multi-color liquid crystal display is realized by a display device which includes a liquid crystal panel having a plurality of layers of cholesteric-nematic phase transition type liquid crystals having a positive dielectric anisotropy and phase transition hysterisis when a voltage is applied. The liquid crystals are driven to be in homeotropic and focalconic textures which are maintained when at a certain voltage is applied thereto. A desired color of the projected display can be obtained by selecting a thickness of the liquid crystal layer and a refractive index anisotropy of the liquid crystal of the liquid crystal layers.
