Plasma display panel

A plasma display panel including a plurality of row electrode pairs extending in a row direction and arranged in a column direction to form display lines and a dielectric layer overlaying the row electrode pairs on a backside of a front substrate, and a plurality of column electrodes extending in the column direction and arranged in the row direction to constitute unit light emitting areas in the discharge space at respective positions, corresponding to intersections of the column electrodes and the row electrode pairs, on a face of a back substrate facing the front substrate with a discharge space in between, said plasma display panel comprising:

• a partition wall arranged between said front substrate and said back substrate, and having vertical walls extending in the column direction and the transverse walls extending in the row direction to define said discharge space into each of the unit light emitting areas in the row direction and the column direction;
• a clearance extending in parallel to the row direction, and separating the transverse wall situated between the adjacent unit light emitting areas respectively in the column direction;
• and
• a communicating section for making communication between the inside of said clearance and the inside of the discharge spaces in the adjacent unit light emitting areas in the column direction.
