PROBLEM TO BE SOLVED: To provide an adhesive optical film with an adhesive layer arranged thereon to stick an optical film to a glass substrate of a liquid crystal panel, having excellent durability even under a condition such as heating and humidifying, bringing about little variation in dimensions of a base material forming the optical film and little failure caused by the adhesive. SOLUTION: In the adhesive optical film with the adhesive layer to stick the optical film to the glass substrate of the liquid crystal panel laminated on one surface of the optical film, the adhesive optical film is characterized by having <=0.08% dimensional coefficient of expansion of the optical film generated after being let alone for 24 hours in a 60 deg.C/90%RH(relative humidity) atmosphere, and having <=0.20% dimensional coefficient of contraction of the optical film generated after being let alone for 100 hours in a 90 deg.C/5%RH atmosphere in a state in which the adhesive layer of the adhesive optical film is stuck to the outermost surface of the liquid crystal panel and fixed. |
