Abstract
In a plasma display panel, a partition wall 15 surrounds each of discharge cells to define the discharge cells. Each of the discharge cells is divided by a second transverse wall 15B into a display discharge cell C1 which is opposite transparent electrodes Xa, Ya of paired row electrodes X, Y to provide for a sustaining discharge; and an addressing discharge cell C2 which is opposite a bus electrode Yb of the row electrode Y to provide for an addressing discharge caused between the bus electrode Yb and a column electrode D. A clearance r is provided between the discharge cell C1 and the addressing discharge cell C2 for communication between the cells C1 and C2.
Claims37
A plasma display panel, including:
- a front substrate;
- a plurality of row electrode pairs arranged in a column direction on a back surface of the front substrate, and each extending in a row direction and forming a display line;
- a dielectric layer covering the row electrode pairs on the back surface of the front substrate;
- a back substrate placed opposite the front substrate with a discharge space interposed;
- and
- a plurality of column electrodes arranged in the row direction on a surface of the back substrate facing toward the front substrate, 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, said plasma display panel comprising:
- partition walls surrounding each of said unit light-emitting areas to define the unit light-emitting areas;
- a dividing wall for dividing each of said unit light-emitting areas into a first discharge area facing mutually opposite parts of said respective row electrodes constituting each of the row electrode pairs and providing for a discharge produced between the mutually opposite row electrodes, and a second discharge area facing a part of one row electrode of said row electrodes initiating a discharge in association with the column electrode and providing for the discharge produced between the column electrode and the part of said one row electrode;
- and
- a communicating element provided between said first discharge area and said second discharge area for communication from the second discharge area to the first discharge area.
