A plasma display panel has, on the display-side inner surface of one substrate out of a pair of substrates disposed opposite to each other via a discharge space, plural pairs of row electrodes extending in parallel in a first direction with each discharge gap held therebetween, dielectric layers for the row electrodes with respect to the discharge space; and on the back-side inner surface of the other substrate disposed opposite to the display-side substrate, plural pairs of column electrodes extending in a second direction perpendicularly crossing the first direction and forming unit luminous areas in intersecting portions with respect to the respective pairs of row electrodes, and belt-like partition walls for partitioning the discharge space into the unit luminous areas in the first direction. The row electrode includes a transparent conductive film having a body portion extending in the first direction in the proximity of the discharge gap and a projecting portion projecting in each unit luminous area from the body portion in a direction away from the discharge gap, and a metal film connected to the leading end portion of the projecting portion of the transparent conductive film and extending in the first direction.

AC-driving plasma display panel of surface-discharge type

A plasma display panel has a first sustain electrode and a second sustain electrode, a plurality of address electrodes disposed in a direction perpendicular to the first and second sustain electrodes. Each of the first and second sustain electrodes is formed by a transparent conductive film and a metallic film mounted on the transparent conductive film. A dielectric layer is mounted on the transparent conductive film and the metallic film. The first sustain electrodes and the second sustain electrodes are alternately disposed at every display line. A surface of the dielectric film corresponding to the metallic film is projected from a surface corresponding to other portions.

Plasma display panel of a surface discharge type and a driving method thereof

A plasma display panel has a plurality of first and second sustain electrodes, a plurality of address electrodes which intersect with the sustain electrodes to form a pixel at every intersection. In the method, an address period is provided, in which data pulses are applied to the address electrodes, and scanning pulses are applied to the second sustain electrodes, thereby selecting lighted pixels and unlighted pixels. A discharge sustaining period is provided, in which discharge sustaining pulses are alternately applied to the first and second sustain electrodes so as to sustain the lighted and unlighted pixels. An offset voltage having the same polarity as the data pulse is applied to the address electrodes in the discharge sustaining period.
