<p>The invention relates to a method for manufacturing an optical film. The method includes an unwinding step, a cleaning step and an application step. In the unwinding step, a long-band shaped flexible base having a first principal surface and a second principal surface is unwound from a continuous roll, and the base is continuously fed to a downstream side. In the cleaning step, a cleaning liquid is supplied between the second principal surface of the base and a cleaning roll, and the cleaning liquid is applied and spread over the base by the cleaning roll to clean the second principal surface of the base. Thereafter, in the application step, a resin solution is applied onto the first principal surface of the base and then the resin solution is dried.</p> |
