Abstract

The present invention consists of a method for manufacturing an optical film, a paper-threading method for the film, a manufacturing device used in the manufacturing method, an optical film made by the manufacturing method, and an image-displaying device provided with the optical film. The manufacturing method for the optical film can stretch the film without breaking it; hence, the productivity rate is increased. The manufacturing method for the optical film is a method in which the film is immersed in a solution. The manufacturing method for the optical film is as follows: when the film is not yet in contact with the solution, the film is disposed on at least one pair of transmitting rollers that revolve in a specific transmitting direction, stretching the film tight and immersing it in the solution.
