Abstract
The object of the present invention is to provide a wire grid type polarizer formed of an inexpensive material in a comparatively simple process. A wire grid type polarizer of the present invention comprises: a substrate which prevents light in a specific wavelength range from being transmitted therethrough; and a photoresist layer provided on a surface and a back of the substrate, wherein parallel line patterns having a plurality of concave-convex portions are formed on the photoresist layer to be in parallel with each other on the surface and the back of the substrate, and a metal is deposited only over a top of a convex portion of the parallel line patterns having the concavo-convex portions formed on the surface and the back of the substrate and in the vicinity thereof so that a wire grid is formed on the surface and the back of the substrate.
