A plasma display apparatus is provided that includes a front substrate, a first electrode, a second electrode and a dielectric layer formed on the front substrate, a rear substrate faced with the front substrate, a third electrode formed on the rear substrate, and a barrier rib which is formed on the rear substrate and partitions discharge cells, wherein at least one of the first electrode and the second electrode is formed with one layer, and the width of at least one of barrier ribs which partitions the discharge cells in the outside of an effective display region is wider than the width of barrier ribs which partition the discharge cells in the inside of the effective display region. The plasma display apparatus does not include a transparent electrode consisting of ITO, reducing the manufacturing cost of the plasma display panel. Further, by forming projecting electrodes protruded in the direction of the center of the discharge cell or in the opposite direction of the center of the discharge cell from the scan electrode or the sustain electrode line, the firing voltage can be lowered and the discharge diffusion efficiency of the discharge cell increased.

Plasma display apparatus

A plasma display apparatus is provided. The plasma display apparatus including an upper substrate; a plurality of first electrodes and second electrodes formed in the upper substrate; a lower substrate arranged to be opposite to the upper substrate; and a plurality of third electrodes and barrier ribs formed in the lower substrate includes a black matrix formed in the upper substrate to be overlapped with the barrier ribs; and a fourth electrode formed on the black matrix to intersect the third electrodes, wherein at least one of the plurality of first and second electrodes is formed in one layer.

The present invention relates to a plasma display apparatus, which includes a front substrate; a plurality of first, second electrodes formed on the front substrate; a rear substrate that is faced with the front substrate; a plurality of third electrodes formed on the rear substrate; and a discharge cell that is disposed in the place where the first, the second electrode intersect with the third electrode, wherein at least one of the first and the second electrode is formed with one layer, wherein the width or the length of the first and the second electrode arranged in the adjacent discharge cells are different each other. Accordingly, the manufacturing cost can be decreased by eliminating the transparent electrode made of ITO, the color temperature and the luminance of the plasma display panel ca be increased by asymmetrically forming R, G, B discharge cell.

A plasma display apparatus is provided that includes a front substrate, a plurality of first and second electrodes formed on the front substrate, a rear substrate that is faced with the front substrate, a plurality of third electrodes formed on the rear substrate, and a discharge cell that is disposed where the first, and second electrodes intersect with the third electrode, wherein at least one of the plurality of the first and second electrodes is formed with one layer, wherein a thickness of at least one of the plurality of the first and second electrodes ranges from 3 &#x3bc;m to 7 &#x3bc;m. By removing the transparent electrode consisting of ITO, the manufacturing cost of the plasma display panel may be reduced. Further, by forming projecting electrodes protruded to the opposite direction of the center of the discharge cell or in the direction of the center of the discharge cell from the sustain electrode line or the scan electrode, the firing voltage may be lowered, and the discharge diffusion efficiency in the discharge cell increased.
