A plasma display panel for preventing a discharging operation in a non-displaying area and thus progressing the contrast ratio according to the present invention is disclosed. The plasma display panel comprises a first substrate and a second substrate which are provided with each of inner faces opposite to each other. Between the first and second substrates, barrier ribs arranged toward a first direction are separated parallel to each other with a space. On the inner face of the first substrate, first electrodes are arranged parallel with each other toward a second direction which is orthogonal with the first direction. In addition, dot type second electrodes, which are connected with a pair of first electrodes and are exposed to a space between the pair of first electrodes, are arranged on the inner face of the first substrate. Between the barrier ribs on the inner face of the second substrate, there are placed third electrodes which are arranged parallel with the first direction. Here, a unit cell is defined as an area which is limited by the barrier ribs and includes a pair of first electrode.
