发明名称 Transflective liquid crystal display device having particular angle between initial liquid crystal alignment direction and pixel electrode projection direction
摘要 In a transflective liquid crystal display device, assuming that a narrower angle among angles formed by the initial liquid crystal alignment direction of a liquid crystal layer, and the projection direction of a pixel electrode of a transmissive unit is &thetas;t and that a narrower angle among angles formed by the initial liquid crystal alignment direction of the liquid crystal layer, and the projection direction of a pixel electrode of a reflective unit is &thetas;r, (1) when the liquid crystal layer possesses a positive-type liquid crystal, the relation of &thetas;t>&thetas;r is satisfied, and (2) when the liquid crystal layer possesses a negative-type liquid crystal, the relation of &thetas;r>&thetas;t is satisfied. The relations are satisfied by slanting or bending at least one of the pixel electrodes, and the reflectivity is improved.
