Patent ID: 7667404

Claim:
A plasma display apparatus, comprising: three or more cells arranged on a rear surface substrate to be partitioned off by barrier ribs in a delta configuration; data electrodes arranged under the cells and having wide parts corresponding to discharge spaces within the cells and narrow parts extending between the wide parts; pairs of sustain electrodes arranged on a front surface substrate attached to the rear surface substrate to at least partially overlap the barrier ribs; and extension parts extended from respective sustain electrodes of at least one of the pairs of sustain electrodes into a corresponding one of the cells to face each other, each extension part having at least one recess that overlaps and extends substantially in a same direction as the data electrodes, wherein a distance between the recesses of the extension parts is greater than a distance between other areas of the extension parts in said one of the cells, wherein each extension part and the at least one recess of each extension part are aligned with a wide part of a corresponding one of the data electrodes, and wherein the wide part of said corresponding one of the data electrodes is aligned with a central area of the discharge space of said one of the cells.
