11 Claims

1. An adhesive film formed of a cured adhesive composition comprising: a copolymer of a monomer mixture comprising a hydroxyl group-containing (meth)acrylate and a comonomer; and nanoparticles, wherein the adhesive film has a creep at −20° C. of about 50 μm to about 100 μm and a storage modulus at −20° C. of about 30 kPa to about 100 kPa, wherein the nanoparticles have an average particle diameter of about 5 nm to about 400 nm, and

wherein the nanoparticles are present in an amount of about 0.1 parts by weight to about 10 parts by weight relative to 100 parts by weight of the monomer mixture,.

wherein the hydroxyl group-containing (meth)acrylate is a C₁to C₂₀alkyl group-containing (meth)acrylic acid ester having at least one hydroxyl group, a C₅to C₂₀cycloalkyl group-containing (meth)acrylic acid ester having at least one hydroxyl group, or a C₆to C₂₀aryl group-containing (meth)acrylic acid ester having at least one hydroxyl group, and

the comonomer includes at least one of alkyl (meth)acrylate monomers, ethylene oxide-containing monomers, propylene oxide-containing monomers, amine group-containing monomers, amide group-containing monomers, alkoxy group-containing monomers, phosphoric acid group-containing monomers, sulfonic acid group-containing monomers, phenyl group-containing monomers, or silane group-containing monomers.
