Abstract:
A display optical system comprising:an illumination optical system for emitting illumination light; a plurality of reflection-type display devices for individually modulating the illumination light emitted from the illumination optical system and reflecting the illumination light thus modulated as projection light; a projection optical system for projecting the projection light, the projection optical system having at least one optical element included therein arranged so as to be decentered with respect to other optical elements included therein; and a plane-parallel mirror for separating the illumination light into light components by reflecting a part and transmitting another part of the illumination light and then directing the light components thus separated individually to corresponding ones of the reflection-type display devices, and for integrating together the projection light reflected individually from the reflection-type display devices and then directing the projection light thus integrated together to the projection optical system.
