  • LC display device with parallel field component
    Patent number: 7656490
    Abstract: An electro-optical display device comprising a liquid crystal layer achieves switching using an electric field component which is predominantly parallel to the surface of the liquid crystal layer. Low dependence of image contrast on viewing angle is achieved by selection of parameters including pretilt angle ?0, orientation angle ?0, etc. of the liquid crystal molecules in the layer.
    Type: Grant
