<P>PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive optical film which includes a discotic liquid crystal layer with a discotic liquid crystal compound aligned on one surface of a transparent base material film, in which a pressure-sensitive adhesive layer is laminated on the discotic liquid crystal layer, and which has superior durability, display uniformity, and handling properties. <P>SOLUTION: In the pressure-sensitive adhesive optical film in which a pressure-sensitive adhesive layer 5 is provided on the discotic liquid crystal layer of the optical film including the discotic liquid crystal layer 3 on one surface of the transparent base material film 1 via an undercoat layer 4, the undercoat layer includes polymers and an anti-oxidizing agent, the pressure-sensitive adhesive layer is formed of an adhesive including an acrylic polymer, a cross-linking agent, and a silane coupling agent, the acrylic polymer includes alkyl (meth)acrylate (a1), (meth)acrylate (a2) including an aromatic ring structure, and a monomer (a3) excluding the (a1) and (a2) components. <P>COPYRIGHT: (C)2010,JPO&INPIT |
