Provided is a method of manufacturing a wire grid polarizer in which a stable color coordinate can be implemented. According to the present invention, in a process where a second grid pattern of metal pattern is formed over a first grid pattern made of resin material, metal layer is deposited in a concave portion formed between adjacent first grid patterns to form void portion and a width and a height of the second grid pattern are adjusted depending on adjustment of a width of the voids, and thereby improving a process efficiency.
