ABSTRACT:
Provided is a method of nano-patterning block copolymers and a method of manufacturing a polarizer using the same. The method of nano-patterning block copolymers includes coating block copolymers on a lower substrate to a predetermined thickness, forming a thickness gradient by patterning the block copolymers to have a predetermined aspect ratio, and aligning self-assembled block copolymers in a direction of the thickness gradient by heat-treating the block copolymers having the thickness gradient.
