Abstract
An electroluminescent D.C. display panel has a transparent substrate, transparent anodes, a metal oxide interlayer, an electroluminescent powder phosphor, and cathodes formed in stacked relation on the substrate. The metal oxide interlayer allows the panel to be formed relatively quickly at substantially reduced forming currents.
