titleOfInvention | Production method of retardation film and retardation film produced by the method |
abstract | Kind Code: A1 It is possible to suppress a difference in thickness between an end portion and a central portion of a film when a thermoplastic resin film is longitudinally stretched, and a letter between the end portion and the central portion of the film after lateral stretching. Provided are a method for producing a retardation film capable of suppressing the difference in the retardation, and a retardation film produced by the method. When a thermoplastic resin film 12 is longitudinally stretched in the longitudinal direction due to a difference in peripheral speed between a pair of rollers 34, 36, (a) a thermoplastic resin film 12 before longitudinal stretching and a thermoplastic resin after longitudinal stretching. The difference in film width from the film 12 ′ is 50 mm or less, (b) the difference between the thickness De at the widthwise end of the thermoplastic resin film 12 ′ after longitudinal stretching and the thickness Dc at the widthwise center (De−Dc) Satisfies the condition of at least one of 20 μm or less.
