| titleOfInvention | Method for producing stretched film, stretched film, polarizing plate, and liquid crystal display device |
| abstract | The present invention provides a method for producing a stretched film having a slow axis inclined with little variation in optical characteristics. A preheating zone in which a long film made of a thermoplastic resin is fed out from a direction different from a film winding direction D2 after being stretched, and both ends of the film are gripped and transported by grippers CR and CL. , Passing through an oven having a stretching zone and a cooling zone, and producing a long stretched film having an orientation angle θ in the range of 40 to 80 ° with respect to the winding direction. A long film made of a plastic resin has a thickness variation σm in the flow direction and a thickness variation σt in the width direction of σm <0.30 μm and σt <0.20 μm, and the take-up tension T of the stretched film is 100 N. / M <T <300 N / m, and the variation of T is less than ± 5%.
