    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 provided on one side of the transparent base film; an undercoat layer; and a pressure-sensitive adhesive layer provided on the discotic liquid crystal layer with the undercoat layer interposed therebetween, the undercoat layer comprises a polymer and an antioxidant; and the pressure-sensitive adhesive layer comprises a (meth)acrylic polymer (A) comprising 80 to 99.5% by weight of an alkyl (meth)acrylate monomer unit and 0.05 to 3% by weight of a hydroxyl group-containing monomer unit and having a weight average molecular weight of 1,000,000 to 2,500,000; a (meth)acrylic oligomer (B) comprising 80 to 99.9% by weight of an alkyl (meth)acrylate monomer unit and 0.1 to 3% by weight of a carboxyl group-containing monomer unit and having a weight average molecular weight of 3,000 to 8,000; a crosslinking agent (C); and a silane coupling agent (D), and the pressure-sensitive adhesive layer comprises 10 to 40 parts by weight of the (meth)acrylic oligomer (B) based on 100 parts by weight of the (meth)acrylic polymer (A). The pressure-sensitive adhesive optical film has durability and can suppress display unevenness in a peripheral portion of a display screen and window frame unevenness in a state that a backlight is on.
