The adhesion of a sputter-resistant layer is improved by providing the layer with a fairly high quantity of glass frit, in which the frit and the sputter-resistant material have a mass ratio Mfrit/Msrm of 0.9 or more.
Claims9
A picture display device comprising at least one compartment containing an ionizable gas, in which walls of said at least one compartment are provided with electrodes for selectively generating plasma discharge of said ionizable gas during operation, and an electro-optical layer of a material having an optical property which is dependent on a discharge state of said plasma discharge, wherein at least one of said electrodes is provided with a layer comprising sputter-resistant material and a frit, in which said frit and said sputter-resistant material have a mass ratio Mfrit/Msrm of at least 1, in which Mfrit and Msrm represent the mass of frit and the mass of sputter-resistant material, respectively, per surface unit.
