PROBLEM TO BE SOLVED: To prevent the production of an alignment defect. SOLUTION: The surface of an alignment layer is continuously rubbed by a rubbing roll 19 while continuously carrying a long film substrate 21 on which the orientation film is formed between the roll 19 and a backup roll 20 oppositely arranged on the lower side of the roll 19. When an adhesive roll 14 arranged on the lower side of the substrate 21 is rotated in the same direction as the rotating direction of the roll 19, the Y component PY of frictional force P by an adhesive roll 14 is applied to the substrate 21 so that the Y component RY of frictional force R to the substrate 21 by the roll 19 is canceled, so that even when the rotational frequency of the roll 19 is increased and rubbing density is increased, the substrate 21 can be prevented from being oscillated and the alignment layer can be uniformly rubbed. Consequently the production of an alignment defect can be prevented. |
