DIFFUSED REFLECTION STRUCTURE AND SURFACE-EMITTING DEVICE COMPRISING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a diffused reflection structure that enables plane emission improving uniformity of brightness.SOLUTION: A diffused reflection structure 41 of the present invention includes a plurality of light passage holes 41a that emit indirect light by diffusion-reflecting incident direct light from a light source at least once on an inside surface, and a scattering part 43 that is arranged on the optical axis of the light source and that diffuses the direct light from the light source by diffusion-reflecting it. The scattering part 43 is arranged in the state of protruding to the side of the light source.
