Patent ID: 7550923

Claim:
A plasma display including a first panel comprising: at least a first array of electrodes that is coated with a dielectric layer and with a protective and secondary-electron-emitting layer, said plasma display comprising at least a second array of electrodes and a second panel leaving between it and the first panel a space containing a discharge gas, the electrodes of the first array and those of the second array being arranged so as to leave discharge regions between them and between the panels, and the walls of these regions being partly covered with a layer of a phosphor suitable for emitting light when excited by the radiation from the discharges emitted between the electrodes in these regions, wherein the interface between the dielectric layer and the protective and secondary-electron-emitting layer is structured so as to have a mean roughness greater than 200 nm and less than 400 nm, said structure and roughness being transferred to the external surface of the protective and secondary-electron-emitting layer and being located in order to backscatter the discharge radiation toward the phosphors.
