Abstract: An article (100) for a display device includes a diffraction grating film (102), a first optically clear adhesive layer (120), and a second optically clear adhesive layer (130). The diffraction grating film includes a base layer (104) and a plurality of microstructures (106) projecting from the base layer. The base layer defines a non-structured surface of the diffraction grating film and the plurality of microstructures define a structured surface of the diffraction grating film opposite to the non-structured surface. The first optically clear adhesive layer is disposed on the structured surface of the diffraction grating film. The second optically clear adhesive layer is disposed on the non-structured surface of the diffraction grating film.

Abstract: Methods for reducing road surface glare from an automotive headlight for an observer not viewing through a polarizing filter are described. The use of a reflective polarizer for reducing road surface glare from an automotive headlight for an observer not viewing through a polarizing filter are also described. A low-beam headlight including a light source, a housing, and a reflective polarizer is also described. The reflective polarizer has a pass axis and the pass axis forms an angle with a road surface between 45 degrees and 135 degrees.
