PURPOSE: A phase difference film, a polarizing plate, and an image display device including the same are provided to improve molding workability without the reduction of heat resistance and transparency of a film. CONSTITUTION: A phase difference film is comprised of an acrylic group copolymer. The acrylic group copolymer comprises a methacrylic group monomer of 70 to 90weight%, a styrene group monomer of 2 to 10weight%, an isobornyl group monomer of 4 to 10weight%, and a maleimide group monomer of 4 to 10weight%. An in-plane phase difference value of the phase difference film is -50 to +50 in 550nm wavelength. A thickness direction phase difference value of the phase difference film is -50 to +50 in 550nm wavelength. |
