METHOD AND APPARATUS FOR CLOSELY BONDING BASAL PLATE AND FILM

PURPOSE:To closely bond a film to a basal plate while the tension of the film is kept constant and to prevent the generation of static electricity. CONSTITUTION:One end of the self-adhesive surface of an optical film 14 is closely bonded to a liquid crystal cell 12 by a pressure roller 13 and the ot...

Zusammenfassung:	PURPOSE:To closely bond a film to a basal plate while the tension of the film is kept constant and to prevent the generation of static electricity. CONSTITUTION:One end of the self-adhesive surface of an optical film 14 is closely bonded to a liquid crystal cell 12 by a pressure roller 13 and the other end of the optical film 14 is held by a suction pad 15. A cell stage 11 is moved in an X-2 direction and, when the close bonding area of the optical film 14 and the liquid crystal cell 12 is widened, the height position of the suction pad 15 is controlled to always make the open angle theta of the liquid crystal cell 12 and the optical film 14 almost constant. The position of the cell stage 11 is controlled to always keep the tension T of the optical film 14 almost constant. By this method, no unreasonable tension acts on the optical film 14 closely bonded to the liquid crystal cell 12 and the optical film 14 is not wrinkled. No static electricity is generated in the optical film.
