Abstract
A luminous gas discharge display including two opposing hermetically sealed plates and a pair of low profile electrode assemblies. At least one of the plates is formed of a transparent material and at least one of the plates includes at least one channel terminating in at least one opening through the plate containing an ionizable gas to define a gas discharge path. The electrode assemblies are positioned externally of the glass plates and in communication with channel. Each electrode assembly includes an outer substrate, an intermediate conductive layer deposited on the outer substrate and an inner emissive layer deposited on the intermediate conductive layer opposite the opening. The intermediate conductive layer provides electrical contact between a voltage source and the inner emissive layer to ionize the ionizable gas and produce a gas discharge display.
