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.
