The present invention relates to a process for the manufacture of a plasma panel comprising two tiles facing each other and containing a plasma discharge gas, at least one of the tiles having an array of electrodes serving to define a number of discharge cells and an array of supporting barriers delimiting the cells, the barriers being made of a material giving them a high and open porosity. According to the process, the barriers are formed in a single step using a paste comprising the said material and an organic resin.

Process for the manufacture of a plasma panel

The invention applies to plasma display panels consisting of two facing plates enclosing a discharge space and comprising an array of discharge cells (X , X , . . . , X , etc.). A display panel according to the invention has at least one porous layer which contains less than 10% of a hardening agent. The porous layer is either a barrier layer or a gettering layer.

Plasma display panel having a porous structure

The present invention relates to a plasma panel comprising a first tile called the rear tile and a second tile called the front tile, the two tiles being joined together with a distance of separation defining a space filled with gas, a first array of electrodes which is formed from a set of two parallel electrodes, called the sustaining electrodes, and which is placed on one of the tiles, a second array of electrodes called the addressing electrodes which is placed on the other tile, and an array of barriers which is placed on one of the tiles parallel to the array of addressing electrodes. According to the invention, the array of barriers is positioned on the tile carrying the first array of electrodes, the barriers having a height of less than the distance of separation between the two tiles and the separation between the two tiles is obtained by specific spacing means.
