PRODUCTION METHOD FOR PLASMA DISPLAY PANEL

摘要

A manufacturing apparatus for a PDP includes a unit for forming a protective layer protecting a dielectric layer on a first plate, a unit for baking a phosphor layer applied on a second plate, a unit for sealing the first and second plates arranged so that the protective layer faces the phosphor layer, and a unit for baking the first and second plates while exhausting a space between them. The four units are placed in one or more closed chamber. When the apparatus is driven, spaces in and between the closed chambers each contain a gas atmosphere with vapor partial pressure of 10mPa or lower, or with a pressure of 1Pa or lower, where the protective layer and the phosphor layer exhibit less water-absorbing property, preventing degradation of the PDP performances. The protective layer does not contact with atmospheric carbonic acid gas, preventing alteration thereof. <IMAGE>
