Abstract
An integrated type optical film with a wire grid polarizer structure and a manufacturing method thereof solves the optical matching problem of conventional optical film and integrates an optical effectiveness with all layers by using non-linear optical theory to redistribute integral polarizing efficiency and transmittance in all layers. The integrated type optical film includes two types of polarizers, a reflective type wire grid polarizer and an absorbing type polarizer. The reflective type wire grid polarizer can reflect an incident polarizing light parallel with a metal grid thereof, and transform and transmit polarizing light perpendicular to the polarizer with secondary transmitting efficiency, so that multi-layered structures are integrated into a polarizer with high polarizing efficiency, high transmittance and light-reflective efficiency.
