The invention is a plasma display panel capable of stabilizing the addressing characteristics. A barrier rib is formed by longitudinal barrier ribs portion orthogonal to the scan electrodes and sustain electrodes on the front substrate, and side barrier rib portions crossing with these longitudinal barrier rib portions, to form cell spaces and form interstice portions between the cell spaces, and priming electrodes for producing a discharge between the front substrate and the rear substrate within the interstice portions are formed. Stable priming discharge is produced with certainty by the scan electrode and the priming electrode, hence decreasing the discharge time lag at the time of addressing and stabilizing the addressing characteristics.
