Abstract

The present invention relates to an acryl-based adhesive composition containing an acryl-based copolymer, which is formed by polymerization of a monomer mixture that contains a (meth)acryl-based monomer having an acetoacetyl group, a (meth)acryl-based monomer having a hydroxy group, a (meth)acrylate monomer having an alicyclic group, and an alkyl (meth) acrylate-based monomer; and a curing agent containing a metal chelate compound and an isocyanate compound, in which the acryl-based adhesive composition has a glass transition temperature of −30° C. or greater after curing; and a polarizing plate and a display device prepared using the same.
