| titleOfInvention | Method for producing retardation film |
| abstract | The present invention has been made to solve the above-described conventional problems, and an object of the present invention is to provide a method for producing a retardation film having a slow axis in an oblique direction with high production efficiency. To do. The method for producing a retardation film of the present invention comprises a step of obliquely stretching a long film, a terminal portion of the long film previously subjected to the oblique stretching step, and joining the long film. And a step of joining the starting end portion of a new long film with an adhesive tape, and before the oblique stretching step, the longitudinal clip pitch of each of the left and right end portions of the film to be stretched is changed. A method for producing a retardation film, which is gripped by variable-pitch left and right clips and performs an oblique stretching process by independently changing the clip pitches of the left and right clips, each of which is an end of the long film The angle formed by the joining line between the part and the starting end of the other long film and the width direction of the long film is −10 ° to 10 °.
