ABSTRACT:
A diffusing plate is formed so as to have a surface having a larger surface roughness than a predetermined wavelength and having an aperiodic roughness shape. A plurality of fine concave/convex portions are formed on the surface so as to be regularly arranged within a cycle equal to and smaller than a predetermined wavelength.
