Abstract
Row electrodes X, Y have bus electrodes Xb, Yb extending in the row direction and a plurality of transparent electrodes Xa, Xa′, Ya, Ya′ extending in the column direction, arranged along the bus electrodes Xb, Yb and connected to the bus electrodes Xb, Yb with intersecting. Each end of the transparent electrodes Xa, Xa′, Ya, Ya′ of one of the row electrodes X, Y and each end of the corresponding transparent electrodes Xa, Xa′, Ya, Ya′ of the other are opposed to each other with a discharge gap g in between. Discharge cells C, C′ are formed in a discharge space between a front glass substrate 10 and a back glass substrate 13, opposing the transparent electrodes Xa, Xa′, Ya, Ya′, which form pairs by opposing each other.

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.
A plasma display panel comprising a plurality of row electrode pairs extending in the row direction on a backside of a front substrate and arranged in the column direction, 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 each row electrode which constitutes said row electrode pair has electrode main body portions extending in the row direction and a plurality of protrusion electrode portion extending in the column direction and arranged along said electrode main body portion to connect with said electrode main body portions,
- wherein an end of said protrusion electrode portion of said row electrode opposes to an end of said protrusion electrode portion of the paired row electrode, 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, and
- wherein said paired electrode main body portions of said row electrode pair are regularly corrugated such that an interval between said paired electrode main body portions is alternately spread and narrowed along the row direction, and each protrusion electrode portion is connected with said electrode main body portion at a position which said interval between said paired electrode main body portions is spread.
