Press apparatus used for manufacturing a liquid crystal panel.

摘要

The press apparatus presses upper and lower glass substrates placed between a pressure-exerting plate (7A) and a pressure-receiving plate (4A) while a seal located around the glass substrates is being heated and melted. The pressure-exerting plate (7A) is supported by a pressure-transmitting plate (5) via three load cells (8A-C) arranged in a triangle. When the difference between the detection signals of the load cells exceeds a predetermined value, it is determined that the glass substrates are not being pressed uniformly and the pressing operation can be stopped. <IMAGE>
