Abstract
A method of efficiently orienting liquid crystal molecules on an orientation film formed on one surface of a film substrate which constitutes part of a liquid crystal display panel. In this method, the film substrate is conveyed between a rubbing roll and a backup roll disposed opposite the rubbing roll such that the orientation film faces the rubbing roll, that the rubbing and backup rolls are rotated in contact with the film substrate to thereby rub the orientation film formed on the film substrate for orienting the liquid crystal molecules. Thus, the orientation film formed on the film substrate is continuously rubbed while the film substrate is being conveyed to thereby achieve efficient rubbing.
