  • Liquid crystal display device having a polymer functioning as an orientation layer and a retarder
    Patent number: 5568294
    Abstract: A liquid crystal display comprises a pair of substrates, transparent electrodes respectively formed thereon and a liquid crystal material layer inserted between the electrodes, and is characterized in that a liquid crystalline polymer orientation layer is formed on at least one of the liquid crystal material layers, and the liquid crystalline polymer orientation layer functions as an optical phase retardation film. The phase retardation of the light transmitting liquid crystal layer is compensated by the liquid crystalline polymer orientation layer, which enhances contrast. The liquid crystalline polymer layer can also be used as an optical phase retardation film.
