Abstract
A wire grid polarizer (WGP) can be durable and have high performance. The WGP can comprise an array of wireson a substrate. An overcoat layercan be located at distal ends of the array of wiresand can span channelsbetween the wires. A conformal-coat layercan coat sidesand distal endsof the wiresbetween the wiresand the overcoat layer. The overcoat layer can comprise aluminum oxide. An antireflection layercan be located over the overcoat layer
