Further, an anti-reflector is disposed on an area other than a light-emitting area, and the moth-eye pattern is disposed on open areas of the anti-reflector. Thereby, it is possible to suppress reflected light and prevent reflection of external light on an area on which the anti-reflector cannot be disposed.
