    • PURPOSE: An acrylic adhesive composition is provided to improve light leakage phenomenon, and to have excellent thermal resistance, and to have high release strength, thereby capable of restraining excitation phenomenon. CONSTITUTION: An acrylic adhesive composition comprises an acrylic copolymer comprising a monomer having a pyrrolidonyl group, and a hardener. The comprised amount of the monomer having pyrrolidonyl group is 11-40 parts by weight in 100.0 parts by weight of the acrylic copolymer. The acrylic copolymer is polymerized of 60-83 parts by weight of (meth)acrylic acid alkyl ester having an alkyl group, 1-10 parts by weight of (meth)acrylic ester having a hydroxy group, and 11-40 parts by weight of a monomer having a pyrrolidonyl group. The acrylic copolymer additionally comprises a silane group. The weight average molecular weight of the acrylic copolymer is 800,000-1,500,000 g/mol.
