Abstract
The invention concerns a faceplate comprising, for each discharge zone, at least two electrode elements having an axis of symmetry Ox and which are adapted such that the surface potential V(x) measured at the dielectric layer surface covering said elements increases, away from the edge of the discharge elements, continuously or discontinuously, without decreasing portion, when a constant potential difference is applied between the two electrodes serving said discharge zone, thereby substantially enhancing the panel luminous efficacy.
