Patent ID: 6877858

Claim:
A projector apparatus comprising: a color separation optical system which separates illumination light into red-band light, blue-band light and green-band light components; a first image forming panel illuminated with said red-band light component; a second image forming panel illuminated with said blue-band light component; a third image forming panel illuminated with said green-band light component; a color synthesis optical system which synthesizes the light components from said first image forming panel, said second image forming panel and said third image forming panel illuminated; a projecting optical system which projects light from said color synthesis optical system; and optical elements for adjustment of polarization condition each arranged on incident and exit surface sides of said first image forming panel, said second image forming panel and said third image forming panel, each of said optical elements including a substrate, wherein a thickness of said substrate of said optical element arranged on exit surface side of said first image forming panel is larger than those of said substrates of said optical elements arranged on exit surface sides of said second and third image forming panels in said optical elements each arranged on exit surface side of said first image forming panel, said second image forming panel and said third image forming panel.
