    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.

    摘要: A field effect type liquid crytal display device suitable for use in a high level multiplexing drive, has liquid crystal molecules twisted with an angle from 180.degree. to 350.degree. which are held between two polarizers. The liquid crystal display device generates an interference color due to a birefringent effect of liquid crystal. The occurrence the of this interference color can be prevented by laminating color compensation plates but if the thickness of the optical system increases, a deviation in a display position or a change in the contrast occurs dependent on the observing direction. A phase compensation for the color interference of the liquid crystal is achieved by setting the retardation of the liquid crystal cells having a large twist angle of the liquid crystal molecules and by laminating thin phase plates. Thus, the display quality is improved and the optical axis of an achromatic display can be easily adjusted.
