The disclosure provides: a pressure-sensitive adhesive composition for a flexible image display device; a pressure-sensitive adhesive layer for a flexible image display device; a laminate for a flexible image display device, which, as a result of using the pressure-sensitive adhesive layer and au optical laminate, exhibits excellent bending resistance and adhesiveness, and does not peel even after repeated bending; and a flexible image display device. The pressure-sensitive adhesive composition includes a (meth)acrylic polymer including as monomer units: at least one monomer having a reactive functional group selected from the group consisting of hydroxyl group-containing monomers, carboxyl group-containing monomers, amino group-containing monomers, and amide group-containing monomers; and a (meth)acrylic monomer having a linear or branched alkyl group of 1 to 24 carbon atoms, wherein the monomer having the reactive functional group in all monomers constituting the (meth)acrylic polymer is 0.02 to 10% by weight.
