Phase difference film, a method of manufacturing a phase difference film, a liquid crystal display device and integrated polarizer

摘要

PROBLEM TO BE SOLVED: To provide a retardation film that can adjust the in-plane phase difference and thickness direction phase difference of a film through a stretching method, can manufacture a film having excellent optical characteristics and excellent optical transparency, can solve the disadvantage of a fragile acrylic film through drawing orientation, and has excellent processability and durability including heat resistance.;SOLUTION: There are provided a retardation film that includes a blend resin of (1) an acrylic copolymer resin including an alkyl methacrylate monomer and cycloalkyl methacrylate monomer, and (2) a resin including an aromatic ring or an aliphatic ring in a polymer main chain, a manufacturing method of the retardation film, and a liquid crystal display device including the retardation film.;COPYRIGHT: (C)2015,JPO&INPIT
