在初始液晶取向方向和像素电极投射方向之间具有特定角度的透反射液晶显示装置

Transflective liquid crystal display device having particular angle between initial liquid crystal alignment direction and pixel electrode projection direction
Abstract:
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 θt 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 θr, (1) when the liquid crystal layer possesses a positive-type liquid crystal, the relation of θt>θr is satisfied, and (2) when the liquid crystal layer possesses a negative-type liquid crystal, the relation of θr>θt is satisfied. The relations are satisfied by slanting or bending at least one of the pixel electrodes, and the reflectivity is improved.
