ABSTRACT:
A reflective liquid crystal display and a light diffusion reflector are provided, comprising at least one light diffusion layer and a reflector having one or two reflection angles which exhibit maximums in an angle-dependent distribution curve of reflected light intensity which is generated when light is irradiated on the reflector surface from a direction at an angle of -45 degrees from a normal line to the reflector surface, in which at least one angle exhibiting the maximum deviates by at least 5 degrees from the angle of +45 degrees from the normal line to the reflector surface. The reflective liquid crystal display exhibits a bright image and an excellent visibility of images.
