Patent ID: 7690829

Claim:
A surface light emitter, comprising: a surface light emitting device which generates light itself and emits the light; and a light control sheet which is provided with a concavoconvex structure on at least one surface of the light control sheet and is attached to an emitting side surface of the surface light emitting device, wherein a projection of the concavoconvex structure on the one surface of the light control sheet gets small toward the emitting side surface of the surface light emitting device and has a plane part on a tip of the projection, the plane part on the tip of the projection is bonded to the emitting side surface of the surface light emitting device, so that the light generated by the surface light emitting device enters the projection of the light control sheet through the plane part, and transparent material, whose refraction index is smaller than a refraction index of the light control sheet, is filled in a space between the projection of the light control sheet and the emitting side surface of the surface light emitting device, so that the light generated by the surface light emitting device enters the space directly through the emitting side surface.
