ABSTRACT:
An anisotropic reflection electrode has an undulated shape and whose normal direction is distributed unevenly to a specific azimuth angle and whose reflection light intensity depends on said azimuth angle. Openings are formed in that area of the reflection electrode which has a tilt angle of 0 degree to 2 degrees and/or a tilt angle of 10 degrees or higher. In one aspect, the retardation of a liquid crystal layer is changed by making the liquid crystal molecular alignment mode different between the openings and the reflection electrode, so that the intensity of output light is increased in reflection mode as well as in transmission mode. The balance of colors displayed in transmission mode is determined by determining the area of the openings in pixels of each color, and the color temperature is set higher in transmission mode than in reflection mode. This provides a semi-transmission type liquid crystal display which has an excellent visibility in reflection mode as well as in transmission mode.
