ABSTRACT:
In a method and an apparatus of orientation treatment of an orientation film according to the present invention, the surface of a orientation film formed on a substrate for orientating liquid-crystal molecules is rubbed in a predetermined direction. Thereafter ion beams are radiated onto the orientation film in a vacuum in a direction different from the rubbing direction, that is, in the direction obliquely above the orientation film surface. In the method, these steps can be reversed.
