A wire grid polarizer (WGP) can have a conformal-coating to protect the WGP from at least one of the following: corrosion, dust, and damage due to tensile forces in a liquid on the WGP. The conformal-coating can include a silane conformal-coating with chemical formula (1), chemical formula (2), or combinations thereof: A method of applying a conformal-coating over a WGP can include exposing the WGP to Si(R)(R)(R). In the above WGP and method, X can be a bond to the ribs; each Rcan be a hydrophobic group; each R, if any, can be any chemical element or group; d can be 1, 2, or 3, e can be 1, 2, or 3, g can be 0, 1, or 2, and d+e+g=4; Rcan be a silane-reactive-group; and each Rcan be an alkyl group, an aryl group, or combinations thereof.

Wire grid polarizer with protective coating

A wire grid polarizer (WGP) can have a conformal-coating to protect the WGP from oxidation and/or corrosion. The conformal-coating can include a barrier layer with at least one: of aluminum oxide, silicon oxide, silicon nitride, silicon oxynitride, silicon carbide, hafnium oxide, and zirconium oxide. A method of making a WGP can include applying the barrier layer over ribs of a WGP by vapor deposition.

Oxidation and moisture barrier layers for wire grid polarizer

A wire grid polarizer (WGP) can have a phosphonate conformal-coating to protect the WGP from at least one of the following: corrosion, dust, and damage due to tensile forces in a liquid on the WGP. The conformal-coating can include a chemical: where Rcan include a hydrophobic group, Z can include a bond to the ribs, and Rcan be any suitable chemical element or group. A method of applying a phosphonate conformal-coating over a WGP can include exposing the WGP to (R)PO(R)(R), where: i is 1 or 2, j is 1 or 2, k is 0 or 1, and i+j+k=3; each Rcan independently include a hydrophobic group; Rcan include a phosphonate-reactive-group; each Rcan independently include an alkyl group, an aryl group, or combinations thereof; and each R, if any, can independently be any suitable chemical element or group.
