Abstract
A plasma display panel comprising a plurality of electrodes between a pair of dielectric plates that form gas discharge cells is provided with an additional electrode on one of the dielectric plates to form additional gas discharge cells of an effective discharge area larger than the discharge areas of the cells for use in exhibiting a desired display. The effective discharge area may be enlarged either by the use of a wide additional electrode or by application to the additional electrode of a high-frequency voltage whose peak-to-peak value is higher than that of the high-frequency voltages supplied selectively across the display exhibiting cells.
