ABSTRACT:
Disclosed is a projector apparatus including a color separation optical system which separates illumination light into a plurality of color light components, a plurality of image forming panels illuminated with the plurality of color light components, respectively, a color synthesis optical system which synthesizes the light components from the plurality of image forming panels illuminated, a projecting optical system which projects light from the color synthesis optical system, and transparent substrates each arranged on at least one of incident and exit surface sides of the plurality of image forming panels, each of the transparent substrates holding a polarizer, wherein a surface area of at least one of the plurality of transparent substrates is larger than those of the remaining transparent substrates.
