Abstract

PURPOSE:To prevent a defect such as a dielectric breakdown due to static electricity generated in a rubbing treatment stage by constituting a static electricity removing means at the side of a rubbing material or substrate during the rubbing treatment of a display electrode substrate. CONSTITUTION:Conductive rubbing cloth 3 fixed around a roll 2 is rubbed against the display electrode substrate 1 which has display electrodes and an insulating film for orientation formed on a glass substrate. The substrate is grounded by using the conductive cloth to eliminate electrostatic charging and a defect such as a dielectric breakdown due to the generation of static electricity is prevented, so the multilayered wiring of display elements becomes possible,so that a high-density display liquid-crystal element is easily manufactured.
