Abstract:
1. A plasma display apparatus, comprising: a front substrate; a first electrode, a second electrode, and a dielectric layer formed on the front substrate; a rear substrate positioned adjacent to the front substrate; a third electrode formed on the rear substrate; and a plurality of row barrier ribs and a plurality of column barrier ribs formed on the rear substrate that partition discharge cells, wherein at least one of the first electrode or the second electrode is formed with one layer, wherein the first electrode or the second electrode in an area inside of an effective display region comprises at least two line portions formed in a direction intersecting with the third electrode, wherein the first electrode or the second electrode in an area outside of the effective display region comprises only one line portion, and wherein a width of the line portion in the area outside of the effective display region is wider than a width of each of the at least two line portions in the area inside of the effective display region, and wherein the line portion in the outside of the effective display region parallelly extends on the at least two line portions in the inside of the effective display region, and wherein a dummy cell divided by a dummy barrier rib includes the first electrode and the second electrode in the area outside of the effective display region.
