The invention concerns faceplate, more particularly for plasma display, comprising a substrate on which is provided at least one electrode, made of conductive material consisting of a metal alloy based on aluminium and/or zinc having a melting point higher than 700&deg; C.; the electrode is designed to be coated with a dielectric layer. Thus, the harmful effects derived from reactions of the electrode materials with those of the dielectric layer are limited, in particular when said layer is being cured.

Glass plate provided with electrodes made of a conducting material

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

A plasma panel includes a front faceplate and a rear faceplate between which are constituted cells. The two faceplates are assembled together by bracing means which determine the distance between the two faceplates. The plasma panel further includes barriers arranged between the two faceplates, and serving in particular to prevent the discharges of one cell from extending to the other neighboring cells. The invention is characterized in that the height of the barriers is less than the distance between the faceplates. This arrangement provides a conditioning effect to the cells to thereby enabling them to be activated more speedily. The invention is in particular applicable to plasma panels using luminophores of different colours.
