摘要:
A reflective liquid crystal display apparatus realizing a bright image display without using a backlight is provided. In this reflective liquid crystal display apparatus, a reflecting electrode having a scattering property and a directional property is manufactured using a small number of steps. A pattern of unevenness, such as a polygonal pattern, a cylindrical pattern, and the like, is formed on an insulating substrate utilizing a material layer formed for composing switching devices. By causing the unevenness of the pattern to influence the surface contour of the reflecting electrodes, it becomes possible to give both a scattering property and a directional property to the surface of the reflecting electrodes.
