Abstract

A simple wide-view circular polarizer comprising of a linear polarizer and two biaxial films is proposed. Over the +/-85o viewing cone, the produced polarization is almost circular and the light leakage from the crossed circular polarizers is calculated to be less than 8.23x10(-5), provided that the air-interface surface reflections are ignored. The design tolerance within +/-5% of the optimal parameters is analyzed.
