ABSTRACT:
A method of manufacturing an electric discharge device comprising a pattern of electrodes bonded to a glass substrate. It is necessary for certain gas discharge display devices to use metal electrodes which are at least 20 .mu.m thick and adhere satisfactorily to a glass substrate. A metal foil is placed on a glass substrate 2, and this assembly is heated to a temperature T.sub.1 which is below the melting-point of the metal of the foil and at which the viscosity of the glass of the substrate is in the range from 10.sup.7 to 10.sup.3 Pas. The foil is pressed uniformly against the substrate at the temperature T.sub.1 for a time which is sufficient to produce uniform contact between the foil and the substrate. The foil is then bonded to the substrate by an anodic bonding process, and the desired electrode pattern is produced by locally removing metal from the foil.
