ABSTRACT:
In a concave portion of a reflector of a liquid crystal display, a shape of an opening surface is approximately elliptical. A straight line parallel to a first section line passing through a deepest point of the concave portion along a long axis of the elliptical shape is formed in a portion of the elliptical shape. The concave portion has an asymmetrical shape with respect to the first section which becomes wide from the first section line passing through the deepest point toward a depth direction and has a symmetrical shape with respect to the second section which becomes wide from the second section line perpendicular to the first section line toward the depth direction. A maximum angle of inclination of the second section is larger than a maximum angle of inclination of the first section.
