Abstract:
1. A plasma display panel, comprising: a first substrate; a second substrate arranged so as to face the first substrate and forming discharge spaces in which a discharge gas is enclosed between the second substrate and the first substrate; a plurality of cells formed in the discharge spaces and in which a discharge is caused to occur selectively for display; and a pair of electrodes provided in each of the plurality of cells, respectively, and controlling the discharge, the pair of electrodes comprising edges facing each other for causing a discharge to occur, the distance between the facing edges changing as viewed from a direction perpendicular to the first and second substrates, and the edges have substantially a same shape in each of the plurality of cells, wherein the pair of electrodes comprises: third electrodes are further provided on a dielectric layer covering the first and second electrodes on the first substrate comprising: wherein the second discharge electrode and the third discharge electrode have facing edges and a distance between the edges changes when viewed from a direction perpendicular to the first and second substrates, and wherein the second discharge electrode and the third discharge electrode have edges facing each other and the distance between the edges changes stepwise.
