Abstract
A method of manufacturing a wire grid polarizer for a display apparatus includes the steps of forming a first layer on a base substrate including an active area and a peripheral area surrounding the active area, forming a hard mask layer on the first layer, coating an imprint resin on the hard mask layer, forming an imprint resin pattern by imprinting a stamp on the imprint resin, wherein the stamp is larger than the base substrate, forming a hard mask pattern by patterning the hard mask layer using the imprint resin pattern, forming a wire grid pattern layer by pattering the first layer using the hard mask pattern, forming a photoresist pattern in the active area on the base substrate, removing the hard mask pattern and the wire grid pattern layer in the peripheral area using the photoresist pattern, and forming a capping layer on the wire grid pattern.
