Liquid crystal display and manufacturing method thereof

A method manufacturing a liquid crystal display, the method comprising:

• forming an etch target layer including a conductive material, on a first substrate;
• forming a first mask layer on the formed etch target layer;
• forming a block copolymer coating layer including a plurality of polymers, on the formed first mask layer;
• processing the block copolymer coating layer to form a block copolymer pattern layer including a first polymer block and a second polymer block regularly arranged on the first mask layer;
• removing one of the first polymer block and the second polymer block of the block copolymer pattern layer 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,
• wherein
• the first electrode includes a plurality of first minute patterns which extends in a predetermined direction in a plan view of the liquid crystal display, and having a polarization function on the first substrate such that light passing through the plurality of first minute patterns, is linearly polarized by the plurality of first minute patterns in a direction substantially perpendicular to the extending direction of the first minute patterns.
