Patent ID: 7220371

Claim:
A method for producing a wire grid polarizer, said method comprising the steps of: forming an underlayer of a hydrophilic resin on a substrate; forming a thin film layer of a hydrophobic resin on said underlayer; preparing a die having a plurality of protrusions which extend in parallel to each other and which are spaced from each other at fine intervals; pressing said plurality of protrusions of said die on said thin film layer of the hydrophobic resin until said plurality of protrusions of said die reach said underlayer, to form a plurality of metal fine wire forming grooves in said thin film layer of the hydrophobic resin so that said underlayer is exposed at the bottom of each of said plurality of metal fine wire forming grooves; and forming each of a plurality of metal fine wires in a corresponding one of said plurality of metal fine wire forming grooves by a plating method.
