The circumferential dimension of the rubbing cloth 1 is set to one half or below of the circumferential dimension of the rotational roll 2a, the excentric core irregularities produced by the seam of the rubbing roll 2 are made visually unrecognizable, and the circumferential dimension of the rubbing cloth 1 is reduced, thus reducing the rubbing density and preventing the scraping-off of the orientation film.
