Abstract

A solvent free-type photocurable resin composition for a polarizing plate protective layer includes an acryl-based prepolymer comprising a (meth)acrylate-based monomer as a polymerization unit; and an isocyanate-based crosslinking agent, wherein the acryl-based prepolymer is in a partially polymerized state, and viscosity at 25° C. is greater than or equal to 50 cPs and less than or equal to 300 cPs. A polarizing plate including the solvent free-type photocurable resin composition, and an image display device including the polarizing plate is also provided.
