Zusammenfassung:Provided are an adhesive composition for a foldable display, and an optical member for a foldable display. The adhesive composition for a foldable display comprises: a (meth)acrylic copolymer (A) which contains a hydroxyl group-containing monomer unit (a1), a carboxyl group-containing monomer unit (a2), and an alkyl (meth)acrylate monomer unit (a3), wherein a content of the unit (a1) is 1.5 to 20 mass%, and a weight average molecular weight of the (meth)acrylic copolymer (A) is 1,000,000 or more; a (meth)acrylic copolymer (B) which contains a hydroxyl group-containing monomer unit (b1), wherein a content of the unit (b1) is 3 to 40 mass%, and a weight average molecular weight of the (meth)acrylic copolymer (B) is 2,500 to 10,000; and an isocyanate crosslinking agent. A content of the copolymer (B) is 3 to 50 parts by weight with respect to 100 parts by weight of the copolymer (A). According to the present invention, the adhesive composition for a foldable display is used to form an adhesive layer which is exc
