Abstract: The present disclosure relates to a wire grid enhancement film for displaying backlit and the manufacturing method thereof. The method includes coating a photo-resist layer on a surface of a substrate, adopting a nano-imprinting process to form a nano-scale photo-resist grid on a photo-resist layer, and applying a curing process, and forming a metal film on the cured photo-resist grid. The photo-resist grid is manufactured by roll-to-roll nano-imprinting process. The metal films having cross sections of different shapes may be formed on the cured photo-resist grid. The manufacturing process is simple and the cost may be saved.
