    摘要: Disclosed is to provide a pressure-sensitive adhesive optical film that has excellent durability wherein deterioration of an image display region is suppressed even under severe conditions such as heating caused by lighting of a backlight and to provide a method for producing the same. Disclosed is also to provide an image display using such a pressure-sensitive adhesive optical film. A pressure-sensitive adhesive optical film, comprising: an optical film; and a pressure-sensitive adhesive layer arranged on one or both sides of the optical film, wherein the pressure-sensitive adhesive layer is made from a pressure-sensitive adhesive composition comprising 100 parts by weight of a (meth)acrylic polymer which contains, as a monomer unit, at least 50% by weight of an alkyl (meth)acrylate ester having an alkyl group with 4 or more carbon atoms, and 0.02 to 2 parts by weight of a peroxide, and the pressure-sensitive adhesive layer has a thickness of 20 μm or more.
