A projection display apparatus for combining image lights formed by two or more of different liquid crystal panels through a prism, and projecting the combined image light onto a projection plane through a projection optical system. The apparatus comprises a first optically transmissive substrate opposite an exit plane of the liquid crystal panel, a second optically transmissive substrate opposite an entrance plane of the prism, and at least one third optically transmissive substrate disposed between the first optically transmissive substrate and the second optically transmissive substrate, wherein the first optically transmissive substrate, second optically transmissive substrate, and third optically transmissive substrate are each provided with a polarizer for absorbing a predetermined polarized light component in a predetermined proportion, and the second optically transmissive substrate is adhered to the entrance plane of the prism.
