    摘要: A low color shift polarizer assembly is provided, comprising a cholesteric liquid crystal film with a plurality of very tiny grooves which are irregularly dispersed on a surface of the cholesteric liquid crystal film. The selective reflective wavelength range of the cholesteric liquid crystal film has a long wavelength boundary ≧700 nm and a short wavelength boundary ≦420 nm. A quarter wavelength retardation plate can be disposed on the cholesteric liquid crystal film to build up the final low color shift polarizer assembly. The polarizer assembly can be combined with a backlight unit and further with a liquid crystal display to provide low color shift at large viewing angles and high brightness.

    摘要: A light source module for generating polarized light includes a light emitting element, a reflector, and an optical element. The light emitting element generates a light ray, and the reflector reflects the light ray towards the optical element. The optical element includes a light splitting face and a reflection face. The light splitting face receives the light ray, and an angle between the light splitting face and the incident light ray is at about a Brewster's Angle. After the light ray is irradiated to the light splitting face, the light ray is divided into a refraction light and a reflection light. The reflection face reflects the refraction light, and the reflection face is substantially perpendicular to a path of the refraction light. Therefore, a light source with a high degree of polarization is realized by a design of the light splitting face and the reflection face.
