Patent ID: 7649317

Claim:
A plasma display panel comprising: a first substrate and a second substrate disposed opposite to each other; a plurality of barrier ribs disposed between the first substrate and the second substrate, wherein the barrier ribs define at least one discharge cell; an address electrode formed along a first direction; and a plurality of display electrodes formed along a second direction, wherein the second direction intersects the first direction, wherein a pair of the display electrodes are disposed above the at least one discharge cell with a discharge gap interposed therebetween, and wherein each display electrode comprises: a bus electrode extending along the second direction, an expansion electrode comprising a front end and a back end, wherein the back end is proximal to the bus electrode and the front end extends towards the other display electrode, and an auxiliary electrode disposed at or near the front end of the expansion electrode, wherein the auxiliary electrodes are formed at locations away from central portions of the at least one discharge cell wherein the plasma display panel comprises a plurality of discharge cells, each display electrode comprises a plurality of expansion electrodes, each expansion electrode is dimensioned and configured to correspond to the one discharge cell, and the auxiliary electrodes extend from the expansion electrodes away from the edges of the expansion electrodes in the second direction.
