Abstract: The present invention relates to a process for manufacturing a plasma panel tile, comprising the deposition of electrodes, using a paste comprising a metal powder and a mineral binder, and the baking of the deposited electrodes. According to the invention, the composition of the mineral binder and the baking conditions are tailored so that, after the deposited electrodes have been baked, the binder is in the recrystallized state. Owing to the recrystallized state of the binder, the yellowing problems which occur during subsequent heat treatments are eliminated.

Abstract: The process for manufacturing a plasma display panel, wherein two glass substrates are sealed together using a sealing material of epoxy or polyvinyl butyrate. The sealed structure provides a space between the substrates to contain a discharge gas. The choice of an epoxy or polyvinyl butyrate sealing material allows for relatively low processing temperatures in order to cure the sealing material. This relatively low processing temperature, of between 200° C. and 300° C., lowers the risk of cracking or microcracking of intermediate layers, which are formed on the surfaces of the substrates.
