1. An adhesive film comprising a cured product of an adhesive composition,
wherein the adhesive composition comprises:
an alkyl group-containing (meth)acrylate monomer,
a cycloalkyl group-containing (meth)acrylate monomer,
a carboxyl group-containing monomer, and
an amine group-containing monomer,
wherein the amine group-containing monomer is in a content of 1 part by weight or more and 10 parts by weight or less based on 100 parts by a total weight of monomers, wherein the carboxyl group-containing monomer is in a content of 5 parts by weight or more and 20 parts by weight or less based on 100 parts by the total weight of the monomers, and wherein the adhesive composition does not include a hydroxy group containing monomer, and
wherein the amine group-containing monomer comprises at least one of dimethyl acrylamide, diacetone acrylamide, N[3-(dimethylamino)propyl]methacrylamide, N-methyl-N-vinylacetamide, 2-(dimethylamino)ethyl acrylate, 4-acryloylmorpholine, N-methacryloylmorpholine, N-isopropylacrylamide, 2-methyl-2-oxazoline, 2-ethyl-2-oxazoline, N-isopropyl-2-oxazoline, or ethyleneimine,
wherein the adhesive film satisfies the following Equation 1:
