Electrode configurations for a plasma display panel (PDP) device having one or more substrates and a multiplicity of pixels or sub-pixels that are defined by a hollow plasma-shell filled with an ionizable gas. The invention is described with reference to a plasma-dome, but other plasma-shells may be used including plasma-disc and plasma-sphere. Two or more addressing electrodes are in electrical contact with each plasma-dome, at least one electrode being in contact with a flat side of the plasma-dome. The PDP may include inorganic and/or organic luminescent substances that are excited by the gas discharge within each plasma-dome. The luminescent substance may be located on an exterior and/or interior surface of the plasma-dome and/or incorporated into the shell of the plasma-dome. Up-conversion (Stokes) and down-conversion (Anti-Stokes) phosphor materials may be used. The PDP substrate(s) may be rigid, flexible, or semi-flexible with a flat, curved, or irregular surface.
