Each wireof a wire grid polarizer can include a capon a reflective rib. The cap, with dimensions and material as specified herein, can protect the reflective ribfrom corrosion and can improve performance of the wire grid polarizer. The capcan be located on the distal endand the pair of sidewallsof the reflective rib. Capchemistry can include CO, C═O, COO, aluminum fluoride, and aluminum oxide. Each capcan have a maximum thickness Thon the sidewallof the reflective ribin an upper 50% (above plane) of the wirefarthest from the substrate. Each capcan have a maximum thickness Thon the sidewallthat is greater than a maximum thickness Thof the capon the distal end.

A reflective wire grid polarizer (WGP) can include an array of wireson a face of a substrate, with channelsbetween adjacent wires. The wirescan have certain characteristics for WGP performance, such as index of refraction, alternating high/low index continuous thin films, thickness of layer(s), duty cycle, reflective rib shape, a curved side of transparent ribsor, aspect ratio, or combinations thereof.
