Abstract:
1. A projection display apparatus for projecting light which is formed by two or more different liquid crystal panels and combined by a prism, comprising: a first optically transmissive substrate opposite an exit plane of said liquid crystal panel; a second optically transmissive substrate opposite an entrance plane of said prism; and at least one third optically transmissive substrate disposed between said first optically transmissive substrate and said second optically transmissive substrate, wherein said first optically transmissive substrate, said second optically transmissive substrate, and said third optically transmissive substrate are each provided with a polarizer for absorbing a predetermined polarized light component in a predetermined proportion, and said second optically transmissive substrate is adhered to the entrance plane of said prism, and wherein a gap is defined between said first optically transmissive substrate and said third optically transmissive substrate, and a gap is defined between said second optically transmissive substrate and said third optically transmissive substrate.
