| description | PROBLEM TO BE SOLVED: To perform rubbing treatment with optimum rubbing strength. SOLUTION: A light-detecting part 102 detects surface and bottom reflected light from a substrate 112 on a placement table 100 and plate thickness detecting circuit 103 obtains information on the plate thickness of the substrate 112, based on the result of light detection and outputs the information to a computer 104. The plate thickness of the substrate 112 is calculated by the computer 104. The computer 104 controls a control circuit 106 based on the calculated plate thickness to move the placement table 100 in upper and lower directions and to control the interval between the peripheral surface of a rubbing roller 101 and an alignment layer of the substrate 112 to a specified value. The control circuit 106 controls a substrate surface direction transfer motor 108 to convey the placement table 100 to the lower side of the rubbing roller 101 and to perform rubbing treatment of the substrate 112. Thus, the rubbing treatment using optimum rubbing strength will always be performed, regardless of the fluctuation of the plate thickness of the substrate. |
