Abstract
To improve the front brightness of the light emitted from a surface light emitter having a surface light emitting device. In the surface light emitter to which a light control sheet having depressions is provided, the surface of the light control sheet having the depressions is adhered to a light emitting side surface of a surface light emitting device, and the transparent material whose refractive index is lower than the refractive index of the light control sheet is arranged in the spaces formed between the depressions and the light emitting side surface of the surface light emitting device.
