Abstract
A substrate assembly for a fluorescent or phosphorescent display panel comprises a layer of fired liquid gold, preferably three microns or less thick, for each of segmented display electrodes. The layer is in direct contact with an insulator substrate and with a mass of a luminescent material and may be an integral part of a lead for the electrode or electrodes. Alternatively, the layer may be formed on a resistive layer comprising powder of ruthenium (IV) oxide and formed, in turn, on the substrate with a conductive layer interposed for providing an electric connection to the lead.
