In this paper, we disclose a novel nano‐scale photoaligned liquid crystals polymer thin film polarizer that converts ordinary nonpolarized light to polarized light with efficiency close to 100%, which aims to double the polarization efficiency of conventional polarizers. Different from the mechanisms of conventional film polarizers, which lie in either absorption or reflection and the loss is normally more than 50%, the proposed thin film polarizer is a diffractive polarizer that makes use majority of the incident light and convert it into linear or circular polarized light with minimum loss.
