Title: Manufacturing method of gas discharge panel and sealing device for gas discharge panel
Inventor: OKAWA MASAFUMI
IPC: H01J11/42
Filed: 2002-08-12
Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method capable of stably manufacturing a gas discharge panel comprising a barrier rib top part entirely closely fitted to a panel substrate in the manufacture of gas discharge panels including PDP. SOLUTION: When a process for putting panels 10 and 20 in a heating furnace after forming an envelope 40 for PDP, and sealing the circumferential parts of both the panels together with a sealant is carried out, the pressure is adjusted so that the internal pressure of the envelope 40 is lower than the external pressure. This pressure adjustment is performed, for example, by discharging the internal gas in the envelope 40 by a vacuum pump 52 through a piping member 26. According to this, since the sealing is performed in the state where both the plates are pressed from the outside, they are sealed in the state where the barrier rib top part is entirely closely fitted to the front panel 10.
