A wire grid polarizer comprising a transparent substrate having a first surface. Multiple separate and discrete sections of wire grids can be disposed over the first surface and attached to the substrate, with a border between the sections including an opaque mask material. The mask material can be disposed over the first surface of the substrate. The mask material can be a material different than the wire grid material. The mask material can extend over or under a portion of an edge of the wire grid.
