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.

Disclosed is an optical device comprising a polarizer package comprising an integrated combination of an absorbing layer and a compensator. Two of the identical polarizer packages can be crossed and used in a transmissive optical device. This polarizer package can also be used in combination with a reflective plate and a quarter wave plate in a reflective optical device. Such polarizer packages exhibit an improved viewing angle characteristic across all wavelengths of interest, has a large tolerance for compensators to be aligned relative to their preferred directions, and can be used within an LCD or emissive display system.

An exposure system (5) for fabricating optical film (40) such as for photoalignment, where the optical film (40) has a photosensitive layer (20) and a substrate (10). The exposure system (5) directs an exposure beam from a light source (1) through the optical film (40), then uses a reflective surface (58) to reflect the exposure energy back through the optical film (40) to enhance or otherwise further condition the photoreaction of the photosensitive layer (20).

A display apparatus (30) has an LC device (14) exhibiting its maximum contrast with incident light at an oblique angle φ from normal, wherein oblique angle φ is greater than about +/−10 degrees from normal. A backlight unit (32) provides substantially collimated illumination with a central ray at an incident angle θ2 with respect to the LC device (14), wherein incident angle θ2 within about +/−5 degrees of oblique angle φ. The full-width half-maximum intensity of the illumination is within about +/−10 degrees of the central ray at incident angle θ2.
