    摘要: A pressure-sensitive adhesive optical film of the present invention comprises: an optical film comprising a transparent base film and a discotic liquid crystal layer on one side of the transparent base film; and a pressure-sensitive adhesive layer that is provided on the discotic liquid crystal layer, wherein the pressure-sensitive adhesive layer is made from a pressure-sensitive adhesive containing an acrylic polymer comprising an alkyl(meth)acrylate (a1) and a ring structure-containing (meth)acrylate (a2) as monomer units and having a weight average molecular weight of 1,000,000 to 3,000,000, and a crosslinking agent. The pressure-sensitive adhesive optical film has durability and can be prevented from causing display unevenness in a peripheral portion of a display screen.
