摘要:
A color liquid crystal display includes a cholesteric liquid crystal layer for selectively reflecting at high efficiency circularly polarized light having a specific wavelength, for example, a wavelength corresponding to red, blue or green, a birefringent layer formed on the liquid crystal layer, and a polarize plate formed on the birefringent layer. The birefringent layer includes a pair of electrodes and a nematic liquid crystal layer formed between the electrodes. Circularly polarized light of a specific wavelength that is selectively reflected by the cholesteric liquid crystal layer has its vibration direction rotated by retardation of the birefringent layer 20 when an electric field is not applied to the liquid crystal. When an electric field is applied to the liquid crystal layer, the reflected circularly polarized light is directly transmitted through the birefringent layer. The polarize plate blocks or transmits light according to the vibration direction of the light transmitted through the birefringent layer. This liquid crystal display has high usage efficiency of light and displays color clearly.
