Abstract: The invention relates to an acrylic adhesive composition, more particularly, to an adhesive composition which: specifies the contents of a (meth)acrylic ester-based monomer and an aromatic group-containing monomer of an acrylic copolymer as a composition having little or no difference of birefringence; has excellent durability; and can reduce light leakage due to flexure by mixing a crosslinkable functional group-containing acrylic copolymer (A) and an acrylic copolymer (B) which does not contain the crosslinkable functional group, in a ratio of 1:9 to 5:5.
