Abstract: The invention comprises a process of manufacturing cold cathode gas discharge devices. A unitary metal electrode structure is inserted through a glass support, the metal and glass having the same coefficient of thermal expansion. The support and electrode structure are heated in the presence of oxygen to effect a seal therebetween. The gas discharge device is completed without removing the oxide coating formed on the electrode surfaces of the structure during the heating step. The resulting gas discharge device, which may be used for display purposes, has a stable oxide coating on electrodes thereof that attenuates display distorting reflections.
