摘要： The present invention prevents an unrubbed portion caused by asperities formed on a surface of an alignment layer of a TFT substrate or a counter substrate. A TFT substrate is disposed on a rubbing stage and a projecting portion is formed on a surface of the TFT substrate by TFT wiring. The projecting portion on the surface causes an unrubbed portion, that is, a rubbing shadow particularly at the downstream of rubbing. In a rubbing step, two rubbing rollers that rotate in different directions are provided and the TFT substrate is rubbed in contact with the two rubbing rollers that rotate in different directions, which eliminates the influence of the rubbing shadow. Thus light leakage is prevented in black display.
