ABSTRACT:
A method of manufacturing a flat display panel having first and second substrates assembled in spaced relationship with a gap therebetween and joined together by a band of sealing material, formed in a frame configuration which may be rectangular, on the surface of the first substrate and adhering the first and second substrates together. A paste of the sealing material is dispensed from a nozzle moved along a route from a starting point displaced the frame configuration, thereby forming a starting segment extending from the starting point to the frame, along the route of the rectangular frame configuration and forming a central segment, and from the frame and to the ending point thereby forming an ending segment integral with the central segment, the ending point being displaced from the frame configuration and from the starting point. In one embodiment, the starting and ending segments are tapered, from smaller dimensions at the starting and ending points to greater dimensions, common with the central segment dimensions, and angularly cross each other in overlapped relationship at intermediate positions along the lengths thereof so as to be joined together, at a location displaced from the frame. In another embodiment, the starting and ending segments are displaced laterally so as to extend in parallel and spaced relationship and are joined together by fusing of their contiguous side surfaces.
