Abstract
A surface-emission unit to prevent irregularity in brightness from being generated is provided. The surface-emission unit is composed of light-emission element parts each having a light-emission element, aligned and arranged on a substrate two-dimensionally, and optical lenses each arranged on the substrate with respect to each light-emission element part, to diffuse light from the light-emission element, and a support part to fix the optical lens onto the substrate is arranged so as not overlap a line connecting the light-emission element part corresponding to the optical lens fixed by the support part, to another light-emission element part adjacent to the light-emission element part.
