Abstract: A method for fabricating a wire grid polarizer according to an embodiment comprises: forming a conductive layer on a substrate; forming a guide layer on the conductive layer; forming a hard mask pattern to partially expose the guide layer; forming a guide pattern to partially expose the conductive layer; providing a block copolymer of two monomers having different etching rates; forming two sets of monomer blocks by aligning the block copolymer; selectively removing one set of monomer blocks; and forming a conductive wire pattern using the remaining set of monomer blocks and the guide pattern as etching masks. A width of an upper end of the guide pattern adjacent to the hard mask pattern is smaller than a width of a lower end adjacent to the conductive layer. The width of the upper end of the guide pattern is smaller than a width of the hard mask pattern.

Abstract: Provided is a wire grid polarizing plate. The wire grid polarizing plate comprises a light-transmitting substrate and wire grid patterns which are disposed on the light-transmitting substrate, and which are arranged to transmit first polarized light and to reflect second polarized light polarized in a direction perpendicular to that of the first polarized light, the wire grid patterns comprising target patterns comprising conductive structures shaped as closed curves, at least one of the conductive structures surrounding another one of the conductive structures with a gap therebetween.
