<p>The present invention relates to a method for manufacturing a reflective polarizer, and more specifically to a method for manufacturing a reflective polarizer, including the steps of: coating a block copolymer composed of first and second blocks on a supporter and setting an arrangement direction of the first and second blocks by applying shear force in one direction; thermally processing the block copolymer set in an arrangement direction and separating and arranging the first and second blocks of a lamellae structure; forming a pattern by etching one of the first and second blocks; and forming a metal layer on the block copolymer having the pattern. The present invention can reduce thickness by forming a metal pattern of a single layer, maintain polarization and permeability that are equal to or greater than the polarization and permeability of an absorbing type polarizer, and easily manufacture a large-sized polarizer at a low cost.</p> |
