Wire grid polarizer and backlight unit using the same

Abstract

Provided is a wire grid polarizer and a backlight unit using the wire grid polarizer. The wire grid polarizer comprises a first grid layer thrilled on a substrate and provided with at least one of a first grid pattern, and a second grid layer formed on the first grid pattern and provided with at least one of a second grid pattern made of metal material wherein the first grid layer is made of high molecular substance having a lower refraction index than that of the substrate. According to the present invention, by forming a first grid pattern on a substrate using a high molecular substance layer and by forming a metal grid pattern on the first grid pattern, transmission rates of respective wavelengths depending on light angles of incident light are controlled and thereby minimizing color variations depending on view angle.
