面発光装置の導光板

Light guide plate for surface light emitting device

Abstract

PROBLEM TO BE SOLVED: To provide a light guide plate for a surface light emitting device provided with dots of high light-scattering effect. SOLUTION: In the light guide plate of the surface light emitting device having an emitting surface and a reflecting surface facing each other, wherein a plurality of dots are formed in the reflecting surface to uniformly emit light entering from light sources provided in one end surface or two facing end surfaces from the emitting surface, each dot has a recessed part and a protruded part, and either the recessed part or the protruded part is formed in a ring-shape around the other.
