The light-incident surface includes a plane portion opposed to the light source and an optical function portion that is formed on the plane portion and one of scatters and diffuses the light. The light emitted from the light source enters the light-incident surface. The light that has entered the light-incident surface passes through the light guide portion. The light-emitting surface emits the light passed through the light guide portion.
