Description

In order to solve the above problems, a manufacturing method of the flop plasma display panel of the present invention, as a step for sealing the panel of the rear plate and the front plate, one outside of the back plate or the front plate Forming a sealing material layer including a glass frit at a position to be sealed by the sealing layer in a peripheral region; and the back plate and the front plate so that the sealing material layer contacts the front plate or the back plate. A pre-sealing step of pre-sealing the panel by positioning the face plate facing each other, locally heating an upper end portion of the sealing material layer to join the front plate or the back plate, and pre-sealing the panel by ambient heating panels, and a sealing step for sealing the backplate and the front plate by the entire of the sealing material layer, the sealing material layer is formed of a glass frit Forming a two-layer structure comprising a localized heating sealing material layer forming its upper囲気heating the sealing material layer, in the preliminary sealing step, characterized in that local heating of the local heating sealing material layer.

According to the manufacturing method of the PDP having the above structure, that the panel by local heating of the upper portion of the sealing material layer abolish preliminary sealing. After pre sealing step of a low energy like this, performing sealing by the entire sealing material layer by atmosphere heating panels.
