A plasma display panel capable of reducing a peak value of a sustain discharge current without generating luminance nonuniformity is provided. The plasma display panel comprises: a plurality of first, second, and third electrodes disposed to be adjacent to each other and extending in a first direction, the third electrodes being provided between the first electrodes and the second electrodes where the discharge is repeated; and a dielectric layer covering the electrodes, wherein the space between the first electrode and the second electrode is approximately constant over an entire display area width of the panel, and a space between the third electrode and the first and second electrodes is varied depending on positions in the entire display area width of the panel in a first direction.
