The front luminance of the light emitted from a surface light emitter provided with a surface light emitting device is greatly enhanced. In a surface light emitter in which a light control sheethaving a concavoconvex structure provided on one of its surfaces is affixed on to the light emitting side surface of a surface light emitting device, the projectionson one surface of the above light control sheet gets small towards the light emitting side surface of the above surface light emitting device, not only the tip surfacesof these projectionsare affixed to the light emitting side surface, but also a transparent material with a lower refractive index than the above light control sheet is packed in the space partformed between the projections of the above light control sheet and the light emitting side surface of the surface light emitting device.
