PURPOSE: A plasma display panel, a method of driving the same and a plasma display apparatus are provided to achieve image higher definition by reducing a pixel pitch and increase black display quality reduced by whole-screen discharge light emission during a reset period. CONSTITUTION: A plasma display apparatus comprises a plasma display panel having a substrate, electrodes(X1-Xn+1) formed at the substrate, electrodes(Y1-Yn+1) formed at the substrate, and address electrodes formed at the substrate or at another substrate facing the substrate at a distance, the electrodes being arranged in that order and parallel to one another, an electrode being arranged between an electrode and an electrode for each i = 1 to n in an interdigitate manner, the address electrodes being arranged to intersect the electrodes at a distance; and an electrode drive circuit. The electrode drive circuit includes first field addressing means, for i = 1 to n, for causing a first address discharge to occur between the electrode and the address electrodes selected in correspondence to display data in a first field of a frame and for causing a discharge to occur between the electrode and the electrode using the first address discharge as a trigger to generate a first wall charge required for a sustaining discharge in correspondence to the display data in the first field; first field sustaining means, after the first wall charge having been generated and for odd number o among 1 to n and for even number e among 1 to n, for supplying a first AC sustaining pulse between an electrode and an electrode and for supplying a second AC sustaining pulse between an electrode Ye and an electrode Xe; second field addressing means, for i = 1 to n, for causing a second address discharge to occur between the electrode and the address electrodes selected in correspondence to display data in a second field of the frame and for causing a discharge to occur between the electrode and the electrode using the second address discharge as a trigger to generate a second wall charge required for a sustaining discharge in correspondence to the display data in the second field; and second field sustaining means, after the second wall charge having been generated and for odd number o among 1 to n and for even number e among 1 to n, for supplying a third AC sustaining pulse between the electrode and the electrode and for supplying a fourth AC sustaining pulse between the electrode and the electrode.
