A Plasma Display Panel (PDP) has an opposed discharge structure to reduce its discharge firing voltage and to enhance its luminescence efficiency. The PDP includes: a first substrate and a second substrate arranged to face each other with a space therebetween, the space between the first substrate and the second substrate being divided into a plurality of discharge cells; phosphor layers arranged in the plurality of discharge cells; first electrodes and second electrodes extending in a first direction between the first substrate and the second substrate and alternately disposed in parallel on both sides of respective discharge cells in a second direction intersecting the first direction and shared by adjacent discharge cells, the first electrodes and the second electrodes having floating portions extending toward the second substrate in a direction away from the first substrate and arranged to face one another in spaces corresponding to the respective discharge cells; and address electrodes extending in the second direction between the first substrate and the second substrate, the address electrodes having protruding portions that protrude between the floating portions of the first electrodes and the floating portions of the second electrodes.
