Abstract:
A plasma display panel comprising a plurality of row electrodes extending in the row direction on a backside of a front substrate and arranged in the column direction, a dielectric layer overlaying the row electrodes on a backside of a front substrate, and a plurality of column electrodes extending in the column direction on a surface of a back substrate facing the front substrate with a discharge space in between and arranged in the row direction,wherein said row electrode has electrode main body portions extending in the row direction and a plurality of protrusion electrode portions extending in the column direction and arranged along said electrode main body portions to intersect and connect with said electrode main body portions, wherein said protrusion electrode portions of said row electrode are alternately paired with said protrusion electrodes of said two row electrodes on both sides of the row electrode, an end of said protrusion electrode portion of said row electrode opposes to an end of said paired protrusion electrode portion of the row electrode adjacent thereto, with a required gap in between, and a unit light emitting area is formed in each of said discharge spaces between said back substrate and a section of said protrusion electrode portions paired by said two opposing ends of said protrusion electrode portions, wherein said unit light emitting areas are defined by a partition wall which is disposed between said front substrate and said back substrate, said partition wall is made up by a vertical wall portion which extends in the column direction and a transverse wall portion which extends in the row direction and is arranged to shift by a half length of said unit light emitting area in the column direction every other transverse wall portion, and wherein an additional portion is formed on a portion of said dielectric layer facing said transverse wall portion of said partition wall, to protrude toward said transverse wall portion to shield said adjacent unit light emitting areas from each other in the column direction.
