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.

Reflective wire grid polarizer with transparent cap

A selectively-absorptive wire grid polarizer comprising an array of parallel, elongated rods disposed over a surface of a transparent substrate with gaps between adjacent rods, each of the rods including a reflective wire sandwiched between two absorptive ribs. A method of making this wire grid polarizer. A use of this wire grid polarizer in an image projection system.
