Abstract:
The present invention discloses a light redirecting film, a polarizer with the light redirecting film, and a display comprising the polarizer. The light redirecting film includes a light redistribution layer, and a light guide layer disposed on the light redistribution layer. The light redistribution layer includes a plurality of strip-shaped micro prisms extending along a first direction and arranged at intervals and a plurality of diffraction gratings arranged at bottoms of the intervals between the adjacent strip-shaped micro prisms, wherein each of the strip-shaped micro prisms has at least one inclined light-guide surface, and the bottom of each interval has at least one set of diffraction gratings, and the light guide layer is in contact with the strip-shaped micro prisms and the diffraction gratings. The present light redirecting film is disposed on the viewing side of the display to decrease the light loss in the side viewing angle of the display, and homogenize the brightness distribution at different viewing angles thereof.
