The purpose of the present invention is to provide an adhesive layer attached optical film having excellent durability, in which a display panel is not easily bent, and heat unevenness does not easily occur, even when an optical film to be thinned is used. To achieve the objective described above, an adhesive layer attached optical film (1A) comprises: a first retardation plate (11); a first adhesive layer (21) stacked on a plane of the first retardation plate (11); a second adhesive layer (22) stacked on a surface of the first retardation plate (11), opposite to a surface in which the first adhesive layer (21) is located; and a second retardation plate (12) stacked on a surface of the second adhesive layer (22), opposite to a surface in which the first retardation plate (11) is located. A surface of the first retardation plate (11), in contact with the first adhesive layer (21) is formed of an acrylic resin. According to the adhesive layer attached optical film (1A), a gel fraction of an adhesive forming the first adhesive layer (21) is 55-90%; a storage modulus (G) of the first adhesive layer (21) at 85C is 0.03-0.25 MPa; a gel fraction of an adhesive forming the second adhesive layer (22) is 80-100%; and a storage modulus (G) of the second adhesive layer (22) at 85C is 0.15-3.00 MPa. |
