RUBBING ALIGNMENT TREATMENT DEVICE AND RUBBING ALIGNMENT TREATMENT METHOD OF LIQUID CRYSTAL DISPLAY PANEL

摘要

PROBLEM TO BE SOLVED: To perform rubbing treatment so that eccentric unevenness can not be visualized, to eliminate scraping of an alignment layer due to high speed rotation and to eliminate the problem caused by scrapings, in a rubbing alignment treatment device and its method of the alignment layer 5 of a liquid crystal display substrate 3.;SOLUTION: In the device, the length in the circumference direction of a rubbing cloth 1 is made to be a half or below of the outer peripheral length of a rotary roll 2a, the eccentric unevenness generated by a seam of a rubbing roll 2 is made to be hardly visualized and rubbing density is reduced and scraping of the alignment layer is prevented by shortening the length of the rubbing cloth 1.;COPYRIGHT: (C)2005,JPO&NCIPI
