An AC or DC gas discharge 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 plasma-shell is illustrated with reference to a plasma-dome, but other plasma-shell shapes may be used including plasma-disc and plasma-sphere. A plasma-dome has at least one domed or round side and one opposing flat side such as a dome top and flat bottom or vice versa. One or more other sides or edges may also be flat or non-flat. Two or more addressing electrodes are in electrical contact with each plasma-dome, at least one electrode being in electrical contact with a side or end of the plasma-dome that is not flat. The electrical contact may include a conductive pad in electrical contact with the electrode and/or the plasma-dome.
