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 sheet 10 having 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
projections 12 on 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 surfaces 12a of these projections 12
are 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 part 13 formed between the projections of the
above light control sheet and the light emitting side surface of the
surface light emitting device.
