Patent ID: 8113899

Claim:
A method for producing a plasma display panel, the method comprising: forming a front panel and a rear panel, the front panel being formed to include an electrode A, a dielectric layer A and a protective layer formed on a substrate A, and the rear panel being formed to include an electrode B, a dielectric layer B, a partition wall and a phosphor layer formed on a substrate B; applying a glass frit material onto a peripheral region of one of the substrate A and the substrate B, and subsequently disposing the front panel and the rear panel to oppose one another, such that the applied glass frit material is interposed between the opposing front and rear panels; supplying, via a gas supply device, a gas into a space formed between the opposing front and rear panels, the gas supply device being in contact with a side of the opposing front and rear panels along an entire length of the side of the panels, such that the supplied gas flows between the opposing front and rear panels mostly in one direction, the gas being supplied while the opposing front and rear panels are heated; and melting the glass frit material, so as to seal the opposing front and rear panels.
