Abstract:
A display apparatus comprising:an illumination optical system for emitting illumination light;a reflective display panel divided into a plurality of pixels, said reflective display panel being illuminated by the illumination light from said illumination optical system and selectively reflecting the thus incident illumination light pixel by pixel as projection light;a projection optical system for projecting image information from said reflective display panel onto a projection surface by using the projection light reflected by said reflective display panel; anda reflection angle converting optical system disposed ahead of said reflective display panel,wherein said reflection angle converting optical system is for causing an angle between an optical axis of the illumination light incident on said reflection angle converting optical system and an optical axis of the projection light transmitted by said reflection angle converting optical system to be less than an angle which would be achieved between an optical axis of the illumination light on the reflective display panel and an optical axis of the projection light without said reflection angle converting optical system.
