Gaseous discharge display devices are generally fabricated by forming conductors on glass plates or substrates, overcoating the conductors with a layer of dielectric material, such as lead-borosilicate glass containing a high percentage of lead oxide, and utilizing a coating of refractory high secondary electron emissive material, such as magnesium oxide, over the dielectric layer to protect the dielectric surface against degradation from ion bombardment and provide lower operating voltages. The glass substrates are then edge sealed to form a gaseous discharge display panel, the panel is evacuated, and a Penning gas mixture, such as Ne+0.1%Ar, is introduced into the panel under a less than atmospheric pressure during a backfill operation.
