ABSTRACT:
A pair of dummy orientation film patterns are provided for an orientation film used for aligning LC molecules in an LCD device. For a rubbing treatment of the orientation film, a rubbing cloth is cleaned by one of the dummy orientation film patterns before rubbing the orientation film, and also cleaned by the other of the dummy orientation film patterns after rubbing the orientation film thereby preparing next rubbing treatment for the next LCD device. The dummy orientation film pattern has a thickness larger than the thickness of the orientation film.
