Claim Text:
1. A method of manufacturing a wire gird polarizer, comprising: sequentially stacking a conductive wire layer and a first neutral layer on a substrate; forming guide patterns having a uniform interval on the first neutral layer; reducing widths of the guide patterns and patterning the first neutral layer to thereby form first neutral layer patterns; forming a second neutral layer on a portion of the conductive wire layer between the first neutral layer patterns; applying a first block copolymer of a first monomer and a second monomer having different etch rates to the second neutral layer; arranging the first block copolymer as a first monomer block and a second monomer block; removing one of the first monomer block and the second monomer block; removing the second neutral layer exposed by removing the one of the first monomer block and the second monomer block; removing the remaining monomer block and the guide patterns; applying a second block copolymer of a third monomer and a fourth monomer having different etch rates to the resultant product; arranging the second block copolymer as a third monomer block and a fourth monomer block; removing one of the third monomer block and the fourth monomer block; and patterning the conductive wire layer to thereby form conductive wire patterns.
