<P>PROBLEM TO BE SOLVED: To solve the problem of causing a variation in a discharge characteristic of a panel, since a residual impurity component in a pipe is introduced again in the panel, when sealing discharge gas after evacuation, in a manufacturing device of a plasma display panel PDP. <P>SOLUTION: The reintroduction of the residual impurity component is prevented by complementing the residual impurity component existing on a pipe inner wall outside of a baking furnace 7 by a cooling trap, or by separating a pipe part outside of the baking furnace from a discharge gas introducing pipe passage by a valve in the baking furnace when introducing the discharge gas. In this invention, since influence of an impurity component is not exerted, a variation in the panel discharge characteristic is reduced, and the PDP superior in discharge efficiency and the PDP manufacturing device can be achieved. <P>COPYRIGHT: (C)2009,JPO&INPIT |
