Optically clear adhesive composition, optically clear adhesive film comprising the same, and flat panel display device

The present invention provides an optical transparent adhesive composition, an optical transparent adhesive film comprising the same, and a flat panel display device, the optical transparent adhesive composition comprising a photo-curable (meth)acrylate copolymer, a polydimethylsiloxane-based (meth)acrylate compound, and a photo-polymerization initiator, wherein the photo-curable (meth)acrylate copolymer comprises, relative to the total weight of constituent units contained in the copolymer, 95-99.9 wt% of a hydroxy group-containing acryl-based copolymer and 0.1-5 wt% of an isocyanate group-containing (meth)acrylate-based monomer and the hydroxy group-containing acryl-based copolymer and the isocyanate group-containing (meth)acrylate-based monomer form a urethane bond, and wherein the hydroxy group-containing acryl-based copolymer comprises, relative to the total weight of monomers contained in the copolymer, 50-98 wt% of a C1-C12 linear or branched chain alkyl (meth)acrylate monomer and 2-50 wt% of a hydroxy
