Abstract:
1. A plasma display panel including a pair of substrates opposite to each other with a discharge space interposed therebetween, a plurality of row electrode pairs, each being constituted by a pair of row electrodes, regularly arranged on an inner surface of one substrate of the pair of the substrates in a column direction, and each extending in a row direction to form a display line and being constituted by row electrodes, a dielectric layer provided on the inner surface of the one substrate to cover the row electrode pairs, and a plurality of column electrodes regularly arranged on an inner surface of the other substrate of the pair of the substrates in the row direction, and each extending in the column direction to intersect the row electrode pairs and form display discharge cells in the discharge space at the respective intersections, said plasma display panel comprising: a discharge area provided between adjacent display discharge cells of said display discharge cells in the column direction for producing a discharge between the row electrodes, positioned back to back with each other, of the adjacent row electrode pairs in the column direction, a recess formed in a portion of said dielectric layer facing the discharge area; and a protrusion protruding from a portion of said dielectric layer opposite each of the row electrodes of each row electrode pair toward the other substrate; wherein said recess is formed in a portion of the dielectric layer sandwiched between the protrusions.
