Abstract:
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 provided on an inner surface of one substrate of the pair of the substrates, regularly arranged in a column direction and each extending in a row direction to form a display line, a plurality of column electrodes provided on an inner surface of the other substrate of the pair of the substrates, regularly arranged in the row direction and each extending in the column direction to intersect the row electrode pairs and form unit light-emitting areas in the discharge space at the respective intersections, and a discharge gap provided between a pair of the row electrodes constituting each of the row electrode pairs in each unit light-emitting area, said plasma display panel comprising: a dielectric layer provided on the inner surface of the one substrate to cover the row electrode pairs, and having a thickness in a portion opposite each of the discharge gaps smaller than a thickness in portions positioned on both sides of the portion opposite the discharge gap; a recess provided in a position opposite each of said discharge gaps on the surface of said dielectric layer facing the discharge space to make a thickness of said portion of the dielectric layer opposite the discharge gap smaller than a thickness of said portions of the dielectric layer positioned on both sides of the portion opposite the a pair of protrusions projecting into the discharge space in positions on the surface of said dielectric layer facing the discharge space corresponding to leading ends of the respective row electrodes facing each other with the interposed discharge gap, said recess being formed between the pair of protrusions.
