PURPOSE: A comb-patterned mirror screen is provided achieve a maximized optical efficiency by scattering the greater part of light through a mirror surface at a predetermined angle. CONSTITUTION: A double-sided mirror having a scratched glass surface is arranged in parallelogram, and a plurality of comb teeth pattern plates having an outer slit and an inner slit are combined to form a comb-patterned section surface, so as to thereby improve an optical efficiency. Thus, the projected light is scattered by the scratch while passing through the mirror surface of the comb-patterned plate, thus allowing images to be viewed. |
