Abstract
In an example embodiment, a wire grid polarizer includes a plurality of parallel conductors having a pitch (P), a width (W), and a height (H). In example embodiments, a fill-factor (W/P) is greater than approximately 0.18 and less than approximately 0.25. In another example embodiment, a display system includes a light source and a light-valve. The display system also includes a wire grid polarizer that includes a plurality of parallel conductors having a pitch (P), a width (W), and a height (H). In example embodiments, a fill-factor (W/P) is greater than approximately 0.18 and less than approximately 0.25.
