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(R1)d(R2)e(R3)g.;In the above WGP and method, X can be a bond to the ribs; each R1 can be a hydrophobic group; each R3, 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; R2 can be a silane-reactive-group; and each R6 can be an alkyl group, an aryl group, or combinations thereof. |

1. A wire grid polarizer (WGP) comprising:
a. ribs located over a surface of a transparent substrate, wherein the ribs are elongated and arranged in a substantially parallel array; b. gaps between at least a portion of the ribs; and c. a silane conformal-coating and a phosphonate conformal-coating located over the ribs, wherein the silane conformal-coating includes chemical formula (1), chemical formula (2), or combinations thereof, and the phosphonate conformal-coating includes chemical formula (3): where:
i. is a positive integer;ii. each R1 independently is a hydrophobic group;iii. each X and Z is a bond to the ribs; iv. each R3 and R5 are independently a chemical element or a group. |
