Abstract
A wire grid polarizer includes a substrate adapted to transmit predetermined wavelengths of light, a plurality of dielectric wires extending parallel to one another along a first direction on the substrate, the dielectric wires including a dielectric material adapted to transmit the predetermined wavelengths of light, and a plurality of metal wires extending along the first direction between the dielectric wires, wherein sidewalls of the metal wires include portions in contact with sidewalls of the dielectric wires and portions not in contact with the sidewalls of the dielectric wires.
