The invention relates to a faceplate including a dielectric layer and a protection layer. According to the invention, in order to re-scatter the UV radiation, the interface between the dielectric layer and the protection layer is structured such that it has an average roughness, which is included in the wavelength domain of said radiation, of between 130 and 20 nm in particular. Such re-scattering means are significantly more economical and effective than previous means. The aforementioned roughness can be obtained by performing an abrasion operation on the surface of the dielectric layer.

Plasma panel faceplate comprising UV radiation re-scattering means

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.
