PROJECTION TYPE DISPLAY DEVICE

摘要

PURPOSE:To effectively prevent the non-uniformity of colors on a screen without lowering light emitting luminance. CONSTITUTION:A convex reflector 2 to reflect beams radiated from a light source lamp 1 to an optical system 5 is provided with a first reflecting plane 3 to selectively reflect the green and blue components of beams from the light source lamp 1 to the optical system 5 and a second reflecting plane 4 to selectively reflect the red component to the optical system 5 and to relatively converge this reflected light against the reflected light of green and blue components.
