Each of the light exit areas includes a plurality of light exit parts in which directions of light rays with maximum intensities out of light rays to be emitted are substantially the same. The light exit parts in each of the light exit areas are configured so that the directions of the light rays with the maximum intensities out of the light rays to be emitted from each of the light exit areas are random. Each of the light exit areas has a strip shape, and lengths of the light exit areas are random.
