Abstract: The present invention provides a substrate, wherein a repair structure is arranged on the substrate and used for repairing surface fibres of rubbing cloth. According to the substrate provided by the present invention, by virtue of the repair structure on the substrate, the curvatures of the surface fibres of the rubbing cloth can be the same when the rubbing cloth passes through the repair structure, thus improving the arrangement orderliness of the surface fibres of the rubbing cloth, and then effectively alleviating the phenomenon of poor rubbing.
