Abstract
A rubbing buff is wrapped around a roller so that an axial direction of short fibers on a rubbing cloth crosses diagonally with a roller rolling direction. The roller is placed so that a rotational shaft crosses diagonally with a moving direction of a substrate. Then orientation films formed on an upper and a lower substrates are rubbed by the roller in a first and second directions whereby an orientation direction is determined. As a result, quality display can be realized on an LCD.
