There is disclosed a multiple gaseous discharge display/memory panel having an electrical memory and capable of producing a visual display, the panel being characterized by an ionizable gaseous medium in a gas chamber formed by a pair of opposed dielectric material charge storage members in contact with the gaseous medium, each dielectric being backed on the non-gas contacting side by an array of conductor (electrode) members, the conductor members behind each dielectric material member being appropriately oriented with respect to the conductor members behind the opposing dielectric material member so as to define a plurality of discrete discharge volumes constituting a discharge unit, the gas contacting surface of the dielectric material having a first layer of at least one oxide of Al, Ti, Zr, Hf, and Si and a second layer of lead oxide, both layers being applied to the surface in an amount sufficient to provide substantially lower and more stable panel operating voltages which do not significantly change with panel operating time.
