Title:
Reflective light polarizer which has the angle restrictions to the selected entrance plane and which immersed
Document Type and Number:
Japanese Patent JP6022937
Kind Code:
B2
Abstract:
A film construction includes a broad band reflective polarizing film that may be immersed in an ultra low refractive index medium. The reflecting polarizing film is characterized by a pass axis and a block axis, and its reflectivity for white light of the pass state polarization increases with increasing incidence angle to provide a compressed or narrowed viewing cone selectively in one plane of incidence. In some embodiments, the plane of incidence associated with the compressed viewing cone is aligned with the pass axis. In other embodiments it is aligned with the block axis.
