摘要
The present invention relates to a liquid crystal display, more specifically, relates to a full color cholesteric display employing circularly polarized micro-color filter which is composed of polymeric cholesteric thin film. The display has a long time memory and excellent characteristics of brightness and contrast. A built-in cholesteric color filter structure provides a full color gamut of circular polarization. A cholesteric liquid crystal cell structure, as a circular polarization modulator, provides optical ON and OFF states respectively with its one texture as a circular polarizer and the other texture as a depolarizer. Both of those two textures are electric field controllable.
