The object of the present invention is to provide an adhesive composition for optical films, which can inhibit contamination in the re-release process and peeling under severe conditions with favorably maintaining durability and light leakage prevention property. The adhesive composition for optical films of the invention is an adhesive composition for optical films, comprising (A) an acrylic-based polymer which is obtained by copolymerizing at least the following monomer components: (a1) a (meth)acrylic acid alkyl ester and/or a (meth)acrylic acid alkoxyalkyl ester, (a2) an aromatic ring-containing monomer, (a3) a hydroxyl group-containing monomer, and optionally, (a4) a carboxyl group- or amino group-containing monomer, and which has a weight-average molecular weight of 800,000 to 1,600,000 and a value (Mw/Mn), as obtained by dividing the weight-average molecular weight of the copolymer by the number-average molecular weight thereof, of 10 to 50, (B) an isocyanate-based crosslinking agent, (C) a silane coupling agent, and optionally, (D) a crosslinking accelerator.
