Abstract
A color reflection type polarizer of a high quality and easy to manufacture is disclosed. The color reflection type polarizer is fabricated by disposing an optically anisotropic medium between a reflector and a polarizer, the optically anisotropic medium having a retardation in a plane thereof.
Claims6
A color reflection type polarizer comprising at least one layer of an optically anisotropic medium having a retardation in a plane thereof disposed between a reflector and a polarizer, the value of birefringence at 450 nm of said optically anisotropic medium being in the range of 0.8 to 1.3 times the value of birefringence at 590 nm of the optically anisotropic medium.
