Tilt support ribbed wire grid polarizer

摘要

PROBLEM TO BE SOLVED: To improve the performance of a wire grid polarizer (WGP). Discover a low cost method for manufacturing WGP. A wire grid polarizer (WGP) can include an array of support ribs 92 on a substrate. The side surface of the support rib 92 can be inclined to one side. The wires 132 can be provided on the upper side surface and the distal end of each support rib 92, and each wire is separated from the wires 132 of the adjacent support ribs 92. WGPs can be made with or without etching. [Selection diagram] FIG. 13
