Abstract
A switching element is formed on a substrate disposed proximate a liquid crystal layer. A two layer insulation film is formed on the substrate, including a lower film and an upper film. The two layer insulation film overlays the switching element. A convex/concave structure is formed on an upper surface of the two layer insulation film by removing portions of the upper film. A reflection electrode is formed on a surface of the convex/concave structure.
