Abstract
A white light emitted from a light source is homogenized by an integrator optical system, transmitted through a color polarizer () to be turned into an R light and a G light of a P polarized light, and transmitted through a color polarizer () to be turned into a G light of an S polarized light and an R light of a P polarized light. These R light and G light are subjected to light modulation in a reflection type spatial light modulation element for G and a reflection type spatial light modulation element for R arranged at unequal distances from a polarization split surface of a polarizing beam splitter (), and emitted from a projection lens having an axial chromatic aberration corresponding to the unequal distances.
