Abstract
Disclosed is 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.
