Abstract
A component including a part having a concave and convex configuration for one of the enabling one of light convergence, light diffusion and light diffraction, being formed as a reflective film. The outline of the concave and convex configuration viewed from a right angle relative to a horizontal face has a half moon-shape, and a direction of a straight line part of the half moon-shape of each concave and convex configuration matches a direction of the horizontal face, and a plurality of the concave and convex configurations are combined.
