Abstract
A method of manufacturing a polarizer includes forming a first layer on a base substrate, forming a first partition wall layer on the first layer, forming a second partition wall layer on the first partition wall, forming a plurality of first partition wall patterns and a plurality of second partition walls disposed on the first partition wall patterns by etching the first partition wall and the second partition wall at the same time, forming a block copolymer layer on the first layer on which the plurality of first partition wall patterns are formed, forming a plurality of fine patterns from the block copolymer layer, and patterning the first layer using the fine patterns and the second partition wall patterns as a mask.
