Sealing structure of liquid crystal panel

Abstract

Abstract PURPOSE: To extremely avoid the effect of the outside air and thus enhance the reliability of a liquid crystal panel, by applying the double sealing to the area between a pair of electrode substrates with a thermoplastic nylon and a polyester film. CONSTITUTION: The glass fiber powder that functions as a spacer is scattered onto the back-face electrode substrate 4, and then the thermoplastic nylon film 15 cut into a frame shape is put over the entire circumference of the panel. Furthermore the frame-shaped polyester film 14 having a higher melting point than the film 15 is provided to the inside of the panel (touching the liquid crystal). Then the front-face electrode substrate 2 is put on the film 14, and then a heat pressure process is given at about 180°C and about 30min. Thus the liquid crystal panel is sealed.
