    Abstract: The present invention provides a method for producing a thermoplastic film which makes it possible to improve the optical properties of the thermoplastic film obtained by stretching and a thermoplastic film manufactured thereby. The transverse stretching section in which a cellulose acylate film is transversely stretched includes: a preheating zone, a transverse stretching zone, a cooling zone and a thermal relaxation zone, and the cellulose acylate film having been cooled in the cooling zone is immediately subjected to thermal relaxation treatment in the thermal relaxation zone.

    Abstract: It is an object to provide a method of manufacturing a thermoplastic film capable of improving optical properties of the thermoplastic film obtained by drawing it and to provide the thermoplastic film. In a transverse drawing process part 30 for drawing a thermoplastic film 16 in a transverse direction is constituted by a preheating zone T1 and transverse drawing zones T2, T3 and cooling zones T4, T5, and the steps of the transverse drawing zone T3 and performed thereafter (cooling zone T4 and T5) are maintained at a glass transition temperature Tg or less. The temperature of the preheating zone T1 is set to be higher than that of the cooling zone T4 and falls within the range of -10 C to +30 C relative to those of the transverse drawing zones T2 and T3.

    Abstract: A method of producing a thermoplastic film, which can increase uniformity of Re and Rth of a thermoplastic film obtained by stretching, and which can provide a thermoplastic film having few display irregularities when the film is incorporated into a liquid crystal display device as a retardation film, and a thermoplastic film produced by the method are provided. In a tenter, both ends in the width direction of the film are held with clips and the film is simultaneously stretched in the traveling direction A and the width direction B. By this, a thermoplastic film in which the number of adhesion marks is 10 marks/m2 or less, the in-plane retardation Re is 0 nm to 500 nm and the retardation Rth in the thickness direction is 30 nm to 500 nm is produced.
