Abstract:
1. A method of manufacturing a wire grid polarizer, comprising the steps of: forming a dielectric layer on a region including grid-shaped convex portions of a resin substrate having grid-shaped convex portions and concave portions on a surface thereof; and forming metal wires on one side faces of the convex portions of the dielectric layer by using oblique vapor deposition from one side face of the convex portions in which the metal wires are formed by depositing metal in the direction of an about 30° or less angle formed between the normal of the plane of the substrate and a source of vapor deposition within a plane perpendicularly intersecting a longitudinal direction of a grid of the grid-shaped convex portions, wherein the grid-shaped convex portions of the resin substrate have pitches 150 nm or less and a height 0.5 time to 2.0 times the pitches of the grid-shaped convex portions and the aspect ratio (a ratio being the ratio of the height (H
