Wire-grid polarizers, methods of fabrication thereof and their use in transmissive displays

摘要

Wire-grid polarizers (WGPs) and their use in transmissive displays are disclosed. A WGP (10) comprises an array of spaced-apart, elongated elements (32), comprised of an electrically conductive and reflective material and disposed on a transparent substrate (28), wherein each element (32) of the array has a surface (24) and an opposing surface and wherein the surface (24) imparts a low reflectance to the element (32). The displays containing these WGPs possess high contrast and brightness characteristics in comparison to prior art displays.
