Patent ID: 6995512

Claim:
A plasma display panel comprising: a front substrate having an inner face and a back substrate having an inner face opposing the inner face of the front substrate with a discharge space in between; a plurality of row electrode pairs extending in a row direction and regularly arranged in a column direction to form display lines on the inner face of the front substrate; a dielectric layer covering the row electrode pairs on the inner face of the front substrate; a protective layer covering the dielectric layer on the inner face of the front substrate; a plurality of column electrodes extending in the column direction and regularly arranged in the row direction to intersect with the row electrode pairs; a partition wall having dividing walls; unit light-emission areas formed at the intersections of the row electrode pairs and the column electrodes in the discharge space, and each defined by the partition wall, and each partitioned by the dividing wall into a first discharge area facing mutually opposing portions of the row electrodes constituting each of the row electrode pairs and providing for a discharge produced between the row electrodes, and a second discharge area facing a portion of one row electrode in the row electrode pair initiating a discharge in association with the column electrode and providing for the discharge produced between the column electrode and the portion of the one row electrode; a communicating element provided between the first discharge area and the second discharge area for communication from the second discharge area to the first discharge area; and a secondary electron emissive layer formed of a material of a coefficient of secondary electron emission higher than that of the protective layer and provided on a portion of an inner face of the dielectric layer facing the second discharge area.
