Patent ID: 8232726

Claim:
A plasma display apparatus, comprising: an upper substrate; a first electrode and a second electrode coupled to the upper substrate; a lower substrate disposed to face the upper substrate; and a third electrode and a barrier rib coupled to the lower substrate, wherein first and second black matrices are coupled to the upper substrate and are separated from each other on substantially a same straight line, wherein the plasma display apparatus further comprises a traverse barrier rib to cross the third electrode, and wherein: the first electrode includes a first electrode line and a second electrode line that cross the third electrode, a first protrusion electrode is to protrude from the first electrode line toward a center of a discharge cell, a second protrusion electrode is to protrude from the second electrode line toward the traverse barrier rib, a first region that includes the traverse barrier rib is interposed between the first and second black matrices, and a virtual line extending from the second protrusion electrode overlaps at least part of the first region.
