Claim Text:
1. A rubbing device, comprising: a substrate carrier for carrying a substrate that is to be subjected to alignment treatment, an aligning roller having a surface that is rubbing fabric, a driving mechanism that drives the substrate carrier and the substrate that is to be subjected to alignment treatment carried thereby to undergo a translational movement in a translation movement direction with respect to the aligning roller, and an elevation arm that adjusts a relative vertical distance between a lower surface of the aligning roller and an upper surface of the substrate that is to be subjected to alignment treatment, the relative vertical distance being arranged to have the lower surface of the aligning roller contact and rub the upper surface of the substrate that is to be subjected to alignment treatment and also to have side edges of the upper surface of the substrate that is to be subjected to alignment treatment scrape the lower surface of the aligning roller, the substrate carrier being provided in a top thereof with channels corresponding to two opposite side edges of the substrate that is to be subjected to alignment treatment in the translational movement direction, the channels being arranged to have the two side edges of the substrate that is to be subjected to alignment treatment respectively suspending in the channels.
