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-disc, but other plasma-shells may be used including plasma-dome and plasma-sphere. The plasma-disc has at least two opposing flat sides such as a flat top and flat bottom or a flat rear and flat front. One or more other sides or edges may also be flat. Two or more addressing electrodes are in electrical contact with each plasma-disc, at least one electrode being in contact with a flat side of the plasma-disc.
