An optical assembly including an optical element insert molded directly onto an optical stack is provided. The optical stack includes an optical film and may include a liner with the optical film being disposed between the optical element and the liner. The liner, if included, is removable from the optical film without substantial damage to the optical film. An outermost layer of the optical film may be diffusion bonded to a major surface of the optical element.

Provided is a method of manufacturing a laminated film, the method including laminating a glass film and a resin film via an adhesive layer, by which peeling between the glass film and the resin film is prevented, and hence a laminated film excellent in appearance can be obtained. The method of manufacturing a laminated film of the present invention includes the steps of: laminating a glass film and a resin film via an adhesive to provide a precursor laminate; and curing the adhesive by applying an active energy ray to the precursor laminate, wherein the curing step includes nonuniformly applying the active energy ray in a surface of the precursor laminate.

Shaped optical films and methods of shaping optical films are described. The method includes securing at least portions of a perimeter of the optical film in a first plane so that the secured portions do not move relative to one another; and stretching the optical film by displacing a portion of the optical film along at least a first direction perpendicular to the first plane such that one of a radial and circumferential stretching of the optical film is substantially constant from a center to the perimeter of the optical film, and the other one of the radial and circumferential stretching of the optical film substantially changes from the center to the perimeter of the optical film. The optical film is a reflective polarizer including a plurality of alternating polymeric layers.
