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.

Abstract translation: 为液晶显示装置中的LC分子对准的取向膜提供一对虚拟取向膜图案。 为了对取向膜进行摩擦处理，在摩擦取向膜之前，通过一个虚拟取向膜图案清洁摩擦布，并且在摩擦取向膜之后还用另一个假取向膜图案进行清洗，从而准备下一次摩擦处理 用于下一个LCD设备。 虚拟取向膜图案的厚度大于取向膜的厚度。
