Method of manufacturing pixel electrode for reflection type display device

摘要

A process of a pixel electrode of a direct-sight type of reflection type liquid-crystal display device is simplified. A pixel electrode 120 of a reflection type liquid-crystal display device is formed of an aluminum film which is formed by sputtering. In forming the aluminum film, moisture is intentionally contained in atmosphere, and also a sample is heated. With this process, aluminum grains grow so that irregularities of mu m order is formed on the surface of the aluminum film. The aluminum film thus formed allows the incident light to be irregularly reflected so that it is in a visually white muddy state. This is suitable to the pixel electrode for the reflection type liquid-crystal display device.
