ABSTRACT:
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.
