Abstract
Provided are a wire grid polarizer having a double layer structure, with two metallic wire layers, and a method of fabricating the same. The wire grid polarizer having a double layer structure includes: a light transmitting substrate; a plurality of first conductive metallic wires arranged on the light transmitting substrate parallel to one another at a predetermined period; a light transmitting interlayer arranged on the first conductive metallic wires; and a plurality of second conductive metallic wires arranged on the light transmitting substrate parallel to one another at a predetermined period, wherein the first conductive metallic wires and the second conductive metallic wires are arranged alternately.
