Abstract:
1. A wire grid polarizer device, comprising: a substrate which is transparent to incoming light and having a first surface; at least four separate and discrete sections of wire grids (wire grid sections) disposed over the first surface and attached to the substrate; the wire grids of each wire grid section including an array of substantially parallel, elongated wires configured for polarization of incoming light; a wire grid characteristic of at least one of the wire grid sections is different from a wire grid characteristic of at least one other wire grid section; a border between the wire grid sections including a mask material; the mask material disposed over the first surface of the substrate; the mask material is opaque to incoming light and is a material different than a wire grid material of at least one of the wire grid sections; the mask material extends over or under a portion of an edge of at least one of the wire grid sections; the portion of the edge of the wire grid having mask material extending over or under the edge of at least one of the wire grid sections defines an opaque wire grid section; a portion of at least one of the wire grid sections having no mask material extending over or under the wire grid defines a transmissive wire grid section; an area of the transmissive wire grid section divided by an area of the opaque wire grid section is greater than 1.
