Abstract
The present invention provides a rubbing alignment method of an alignment layer, comprising steps of: step, providing a substrate (), and coating an alignment layer () on the substrate (); step, providing a rubbing roller (), and employing the rubbing roller () to implement a first rubbing alignment to the alignment layer () according to a first rubbing direction; step, employing the rubbing roller () to implement a second rubbing alignment to the alignment layer () according to a second rubbing direction, and the second rubbing direction is opposite to the first rubbing direction. The rubbing alignment method of the alignment layer can effectively eliminate the rubbing shadow to prevent the uneven rubbing alignment and the liquid crystal alignment disorientation to make the liquid crystals in an orderly arrangement. Thus, the light leakage phenomenon of the liquid crystal display panel in the dark state can be suppressed and the contrast ratio can be raised.
