摘要： Provided is a planar light source element array which radiates light having uniform luminance within a surface without generating a lamp image, even a thickness between a target surface and a light emitting element arrangement surface is small. The planar light source element array is provided with a plurality of planar light source elements (5). The planar light source element is provided with a light guide body (1), at least one light emitting element (2) arranged inside the light guide body, a light control member (4) arranged on the bottom surface or the like of the light guide body (1), and a reflecting member (3) arranged on the side surface side or the like of the light guide body. It is so set that the half or more of the light radiated from the light emitting element (2) enters at an angle to be totally reflected inside the light guide body (1) and that the reflecting member (3) returns light into the light guide body (1) by reflection. The light control member (4) is set to change the traveling direction of the reflected light and output the light to the external of the light guide body.
