    Abstract: Provided is a method of fabricating a wire grid polarizer, the method comprising an organic light-emitting display panel. According to an aspect of the present disclosure, there is provided a method comprising sequentially stacking a conductive wire pattern layer, a first neutral layer, a guide pattern layer and a second neutral layer on a substrate, forming etch-stop patterns on the second neutral layer, forming second neutral layer patterns and guide patterns by patterning the second neutral layer and the guide pattern layer using the etch-stop patterns, coating a block copolymer of two types of monomer blocks having different etch rates on the first neutral layer and the second neutral layer patterns, aligning the block copolymer, removing one type of monomer blocks from the aligned block copolymer, and patterning the conductive wire pattern layer using the remaining monomer blocks, the second neutral layer patterns, and the guide patterns.

    Abstract: A manufacturing method of a liquid crystal display includes: forming an etch target layer including a conductive material on a first substrate; forming a first mask layer on the etch target layer; forming a block copolymer coating layer including a plurality of polymers on the first mask layer; processing the block copolymer coating layer to form a block copolymer pattern layer including first and second polymer blocks; removing one of the first or second polymer blocks to form a second mask pattern layer; etching the first mask layer by using the second mask pattern layer as an etching mask to form a first mask pattern layer; and etching the etch target layer by using the first mask pattern layer as an etching mask to form a first electrode. The first electrode includes a plurality of the first minute patterns extending in a predetermined direction and having a polarization function.
