Plasma display panel

A plasma display panel, comprising:

• a front substrate and a rear substrate arranged at an interval to face each other;
• a plurality of barrier ribs arranged between the front and the rear substrates, the plurality of barrier ribs being adapted to partition a space between the front and the rear substrates into a plurality of discharge cells, each of the plurality of discharge cells having one of a circular and an oval cross-section;
• a plurality of upper sidewalls extending from the plurality of barrier ribs towards the front substrate;
• a plurality of discharge electrodes arranged at intervals and within the plurality of upper sidewalls, the plurality of discharge electrodes being arranged in a substrate direction going from the front substrate to the plurality of barrier ribs;
• and
• a plurality of address electrodes arranged a distance apart from the plurality of discharge electrodes in the substrate direction.
