Plasma display apparatus

A plasma display apparatus comprising:

• an upper substrate;
• at least one first electrode and at least one second electrode adjacent the upper substrate;
• a lower substrate arranged to be opposite to the upper substrate;
• at least one third electrode and barrier ribs adjacent the lower substrate;
• a black matrix adjacent the upper substrate and disposed at a location which causes the black matrix to overlap at least one of the barrier ribs;
• a fourth electrode adjacent the black matrix and crossing the third electrode;
• a first line formed to cross the third electrode;
• and
• a second line protruded from the first line, wherein the first electrode, second electrode, and fourth electrode are formed in one layer consisting of only a bus electrode.
