摘要： A method for fabricating a reflective optical film is provided. A substrate is first provided. Next, a phase retardation film is formed on at least one side of the substrate by means of coating. Afterward, a cholesteric liquid crystal (CLC) layer is formed on the phase retardation film by means of coating. Hence, the conventional external bond fabrication process can be simplified. Further, the undesired optical results caused by the more disordered alignment in the upper layer of CLC being more disordered compared to that in the lower layer of CLC and the failure to display the compensation effect can be overcome.

摘要： 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.
