Abstract:
A process for producing an optically anisotropic film component having few defects is provided. The process includes forming a coating continuously on a surface of an elongated film roll, and the process further includes a step of changing the conveyance direction of the elongated film roll on which the coating has been formed while blowing air to a surface of the coating formed on the elongated film roll.
