Abstract: A manufacturing method of a reflective polarizer includes forming a metal layer on a first substrate; forming a mask layer divided into an opening area and a non-opening area on the metal layer, and having grooves patterned in the opening area, the groove exposing the metal layer; increasing hydrophobicity of a surface by treating the mask layer using a silane coupling agent; inducing phase separation of a hydrophilic component and a hydrophobic component of a block copolymer after filling the grooves of the mask layer with the block copolymer; selectively removing the hydrophilic component or the hydrophobic component block copolymer of the block copolymer; and etching the metal layer using the block copolymer as a mask.
