RETARDATION FILM AND A LIQUID-CRYSTAL DISPLAY DEVICE COMPRISING THE SAME

摘要

The present invention relates to a retardation film comprising: 1) an acrylic copolymer resin comprising an alkyl methacrylate based monomer and a cycloalkyl methacrylate based monomer; and 2) a resin blend of resins comprising an aromatic ring or an aliphatic ring on the polymer main chain. The present invention also relates to a production method for the retardation film, and to a liquid crystal display device comprising the retardation film. The retardation film according to the present invention has outstanding properties including heat resistance, optical transparency, mechanical strength and durability.
