摘要：
A diffuser panel having a plurality of micro lenses arranged on a surface of a substrate, a half or more of these micro lenses are in a shape which has (2n+1) angles. This diffuser panel provides rays which are uniformly diffused within a diffusion area and a light amount distribution which changes smoothly. This diffuser panel provides a bright image having a naturally blurred impression when the diffuser panel is used as a focusing panel of an optical apparatus.
