Abstract
[PROBLEMS] To provide an optical film laminate having a thin thickness, excellent durability and excellent productivity and a display device using the laminate. [MEANS FOR SOLVING PROBLEMS] Disclosed is an optical film laminate comprising a polarizing plate having a protective film on at least one surface and a retardation film laminated on the polarizing plate through an adhesive layer, wherein the adhesive layer comprises an active-energy-ray-curable adhesive composition agent comprising (A) urethane (meth)acrylate, (B) a compound which has at least one radical-polymerizable reactive group and at least one hydroxyl or carboxyl group in the molecule and has a molecular weight of less than 200, (C) a compound which has at least one radical-polymerizable reactive group in the molecule and is different from the component (A) or (B), and (D) a photopolymerization initiator. The adhesive agent preferably has a temperature at which the tensile loss factor (tanδ) reaches its maximum upon curing of 0°C or higher in the dynamic mechanical property measurement (measured at a frequency of 1 Hz). The laminate can be used as a component for an image display device such as a liquid crystal display device, an organic electroluminescence display device and a touch panel.
