Abstract: In a preferred embodiment of the present invention, white light emitted from a light source is homogenized by an integrator optical system; the R and the G light component of the white light becomes P polarization light as the white light passes through a color polarizer; and then the G light component is converted into P polarization light while the R light component remains unchanged as the G and the R light pass through another color polarizer. Then, the G and the R light are light-modulated respectively by reflection type spatial light modulation elements for the G and the R light, the elements being disposed so that they have a different distance from a polarizing split face of a polarizing beam splitter. The G light that has been light modulated passes through a lens causing an axial chromatic aberration corresponding to the distance difference and thus exits therefrom.
