| description | Provided is a manufacturing method of an optical film, which manufactures an optical film in which at least a first film and a second film are stacked, the method including: pressing the first film and the second film with the optical film by passing both the first film and the second film between a pair of pressing rolls; forming a slit line in a width direction of the optical film by cutting the second film without cutting the first film at a rear end of a connection portion when the connection portion is included, to which a unit film is connected by a connection member between the first film and the second film which are pressed in the pressing; and conveying the optical film by passing the optical film with the slit line in the slit forming between a pair of conveying rolls. |
