PROBLEM TO BE SOLVED: To simplify a method for forming a pixel electrode of a reflection type liquid crystal display unit. SOLUTION: A pixel electrode 120 of a reflection type liquid crystal display unit is structure from an aluminum film formed by sputtering. When forming a film of this aluminum film, moisture is intentionally contained in the atmosphere, and further a sample is heated. Then, the growth of aluminum particles takes place, and concave and convex parts ofμm order are formed on the surface. Incident lights are diffusedly reflected by the aluminum film, which turns to appear cloudy, and the structure becomes optimum for the pixel electrode of a reflection type liquid crystal display unit.
