摘要： A polarizing plate includes a substrate and a conductive pattern layer including a first pattern and a second pattern. The first pattern includes line-shaped structures disposed at intervals with a period shorter than a wavelength of incident light to be isolated from one another, the first pattern configured to transmit first polarized light of the incident light therethrough and reflect second polarized light of the incident light that is perpendicular to the first polarized light. The second pattern is disposed on an outer boundary of the first pattern, the second pattern isolated and insulated from the first pattern, the second pattern including a stem and at least one branch protruding from the stem toward the first pattern.

摘要： 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.

摘要： A method for manufacturing a polarizer may include forming a first barrier and a second barrier on a surface of a metal layer. The method may further include providing a copolymer layer between the first barrier and the second barrier. The method may further include processing the copolymer layer to form a processed polymer layer that includes first-polymer portions and second-polymer portions that are alternately disposed. The method may further include removing the second-polymer portions from the processed polymer layer to form polymer members that are spaced from each other. The method may further include etching the metal layer, using at least the polymer members, the first barrier, and the second barrier as a mask, to form a plurality of first-type wires and a plurality of second-type wires.
