Abstract
A multi-function integrated polarizer/optical film structure and manufacturing method thereof solves the disadvantages of O type or E type polarizers that cannot simultaneously have high polarizing efficiency and high transmittance. The present invention utilizes optical design for a polarizer/optical film having a plurality of material layers on substrates. The present invention is a multi-function integrated polarizer/optical film structure and manufacturing method thereof, that allows an LCD image to have high polarizing efficiency, high transmittance, wide-angle, high contrast and super-film characteristics simultaneously.
