PROBLEM TO BE SOLVED: To provide an optical film laminated product that reduces uneven change in appearance caused by ambient change, that lowers a defective ratio, and that is also effective for suppressing non-uniformity of display when the product is applied to a display device. SOLUTION: This is the optical film laminated product in which a plurality of optical films are laminated via a pressure-sensitive adhesive. The pressure sensitive adhesives constituting this laminated product are all at least 1.0 N/25 mm in the adhesive strength against 180 degree stripping at a grip travel speed of 300 mm/min for glass. In addition, at least one layer of the pressure-sensitive adhesive is an optical film laminated product whose dimensional change follow-up ratio is not less than 50% relative to the one having the maximum dimensional change ratio among the plurality of optical films. At least one film among the plurality of optical films can be the one formed by stretching a resin film, for example, an absorption type polarizing film or an optical retardation film. Further, it is also effective to a reflection type polarizing film or a light diffusion film. COPYRIGHT: (C)2004,JPO&NCIPI
