Abstract
The present invention provides a method for manufacturing a plasma display panel having a front plate provided with a front substrate, a display electrode formed on the front substrate, a dielectric layer covering the display electrode, and a protective layer covering the dielectric layer. In the method above, after the protective layer has been formed, the front plate is processed in a moisture-free atmosphere for only a period where the front plate has a temperature of 400° C. or lower.
Claims6
A method for manufacturing a plasma display panel having a front plate provided with a front substrate, a display electrode formed on the front substrate, a dielectric layer covering the display electrode, a protective layer covering the dielectric layer, and a back plate sealed with a sealing material to the front plate, the method comprising:
- any one of (i) removing impurity gases attached to the protective layer, (ii) baking a resin component of the sealing material, and (iii) sealing the front plate and the back plate with the sealing material,
- wherein, in the at least one of the removing, baking, and sealing, a temperature of the front plate is decreased to 400° C. or lower after the temperature of the front plate is increased to at least higher than 400° C., and
- wherein the front plate is kept in an H2O free atmosphere for only a period with the temperature of the front plate being 400° C. or lower.
