Abstract: A reflection plate is formed so as to have a wavy surface, and to have uneven distribution of normal line directions of the surface in terms of a specific azimuth angle. The wavy surface is formed due to line-shaped protruding patterns and an insulation film layer. The protruding patterns intersect with one another to form concave portions each having a shape of a closed figure. The protruding patterns are formed by patterning, such that they have almost uniform thickness.
