Abstract
A front plate and a back plate are superposed with each other in parallel, and pressed onto each other. Moreover, the back plate and a gas-blowing jig are brought into close contact with each other. The glass pipe in which a glass fiber filter paper is placed is pressed onto the back plate, with a solid-state glass frit ring interposed therebetween. Thus, by using a glass pipe, a nitrogen, Xe, or Ne gas is supplied into the panel, or the inside of the panel is evacuated.

A method for manufacturing a plasma display panel comprising:
- preparing a first glass substrate having an electrode, a dielectric layer, and a protective layer formed thereon, and a second glass substrate having an electrode, a dielectric layer, a barrier rib, and phosphor layers formed thereon;
- disposing a glass frit on the first or second glass substrate;
- superposing the first glass substrate and the second glass substrate with each other so that a top portion of the glass frit comes into contact with the glass substrate with no glass frit applied thereto;
- disposing a glass fiber member, a glass pipe, and a solid-state glass frit near a through hole formed on the first or second glass substrate;
- blowing a gas into a space between the first and second glass substrates via the through hole formed on the first or second glass substrate, and the glass;
- fusing the glass frit so that the first and second glass substrates are sealed with each other, with the glass pipe being bonded to the first or second glass substrate;
- evacuating a space between the first and second glass substrates;
- and
- enclosing an enclosed gas between the first and second glass substrates.
A plasma display panel comprising:
- a first glass substrate having a protective layer;
- a second glass substrate which is placed so as to be opposed to the first glass substrate to form a discharging space therebetween, with a peripheral portion between the first substrate and the second substrate being sealed with a sealing member, and with a glass pipe for use in sealing a gas into the discharging space or evacuating a gas therefrom being bonded to a periphery of a through hole formed on the first glass substrate or the second glass substrate so as to be connected to the through hole, wherein
- a glass fiber member is disposed on a bonded portion of the glass pipe which is bonded to the periphery of the through hole formed on the first glass substrate or the second glass substrate.
