Abstract:
The present invention provides an optical element, comprising: a side surface where incident light undergoes diffuse reflection inside the optical element, between the outline of a top optical surface and a bottom optical surface; and an inclined surface for total reflection of diffuse reflection from the side surface, formed at least between the side surface and the bottom optical surface.
