Plasma display apparatus

A plasma display apparatus comprising at least:

• a front substrate;
• a plurality of first electrodes and second electrodes extending in a line direction, in which each two thereof are arranged alternately in a row direction on said front substrate;
• a dielectric layer covering said first electrode and said second electrode;
• a back substrate;
• a plurality of address electrodes extending in the row direction, which are arranged on said back substrate in the line direction opposed to said first electrode and said second electrode;
• a plurality of first longitudinal ribs extending in the row direction;
• a plurality of traverse ribs extending in the line direction;
• a plurality of display discharge cells formed by said first longitudinal ribs and said traverse ribs;
• a priming discharge region formed between said traverse ribs of said adjacent display discharge cells of said second electrode, among said display discharge cells adjacent in the row direction;
• a second longitudinal rib extending in the row direction and partitioning said priming discharge region;
• a priming discharge cell formed by said second longitudinal ribs and said traverse ribs;
• and
• a convex electrode extended from said adjacent two second electrodes to said each separate priming discharge cell, on the side facing each other of said two second electrodes adjacent in the row direction;
• wherein there is a gap spatially connecting said display discharge cell and said priming discharge cell, between said front substrate and said traverse rib partitioning said display discharge cell and said priming discharge cell, and said second longitudinal ribs are not present on an extended line of said first longitudinal ribs.

• a priming discharge region formed between said traverse ribs of said adjacent display discharge cells of said second electrode, among said display discharge cells adjacent in the row direction;
• a rib for the priming discharge region, which connects an intersection of said first longitudinal rib and said traverse rib on said priming discharge region side in one said display discharge cell among said display discharge cells sandwiching said priming discharge region and adjacent in the row direction, and an intersection of said first longitudinal rib and said traverse rib on said priming discharge region side in the other said display discharge cell, and extends in a direction different from on the extended line of said first longitudinal rib, and partitions said priming discharge region;
• a priming discharge cell formed by said rib for priming discharge region and said traverse rib;
• and
• a convex electrode extended from said adjacent two second electrodes to said each separate priming discharge cell, on the side facing each other of said two second electrodes adjacent in the row direction;
