Abstract
To provide an adhesive composition for flexible displays having excellent restorability.SOLUTION: An adhesive composition for flexible displays is used to form an adhesive layer 12 for bonding a first flexible sheet 14 to a second flexible sheet 16, the adhesive composition containing a (meth)acrylic copolymer having a first reactive group, and a crosslinker having a second reactive group to react with the first reactive group. An amount of the first reactive groups included in the (meth)acrylic copolymer is 0.002 mmol / g-0.4 mmol / g. A molar ratio of the second reactive groups included in the crosslinker and the first reactive groups included in the copolymer (molar amount of first reactive group / molar amount of second reactive group) is 1 or more. A molar ratio of the first reactive groups included in the copolymer to a blending amount of the crosslinker (molar amount of first reactive group / molar amount of crosslinker) is less than 12.0.SELECTED DRAWING: Figure 1
