PROBLEM TO BE SOLVED: To provide a retardation film which allows an in-plane retardation, a thickness retardation etc. of the film to be controlled through a stretching method, allows manufacture of a film with excellent optical properties and optical transparency, can solve the disadvantage of an acryl-based film being easily broken through stretching alignment, and is excellent in processability and durability such as heat resistance.SOLUTION: A retardation film comprises a blend resin of: an acryl-based copolymer resin that comprises an alkyl methacrylate-based monomer and a cycloalkyl methacrylate-based monomer; and a resin that comprises an aromatic ring or aliphatic ring in a polymer main chain. |
