Patent ID: 7557504

Claim:
A plasma display panel comprising: a first electrode and a second electrode parallel with each other on a first substrate; a third electrode on a second substrate and extending in a direction orthogonal to the first electrode and the second electrode, the second substrate facing the first substrate with a discharge space therebetween; a fourth electrode on the second substrate and parallel to the first electrode and the second electrode; and a first discharge space and a second discharge space on the second substrate and partitioned by a barrier rib, wherein a main discharge cell for performing a discharge with the first electrode, the second electrode and the third electrode is in the first discharge space, and a priming discharge cell for performing a discharge with the fourth electrode and at least one of the first electrode and the second electrode is in the second discharge space, the barrier rib and the first substrate have a clearance therebetween, wherein the barrier rib comprises: a longitudinal rib part extending in a direction orthogonal to the first electrode and the second electrode, and a lateral rib part, extending in a direction orthogonal to the third electrode and parallel with die first electrode and the second electrode, partitioning the first discharge space from the second discharge space, and wherein a pair of first electrodes are arranged next to a pair of second electrodes on the first substrate, and the fourth electrode faces the second discharge space and a plurality of first electrodes which are scan electrodes adjacent to each other.
