<p>A plasma display apparatus according to an embodiment of the present invention includes horizontal barrier ribs and vertical barrier ribs formed on a lower substrate, for partitioning a discharge cell, an address electrode formed under the discharge cell, a scan bus electrode and a sustain bus electrode formed on an upper substrate opposite to the lower substrate, wherein at least one or more of the scan bus electrode and the sustain bus electrode comprise base units crossing the address electrode, and at least two or more projections projecting from the base units in one discharge cell. The base unit or the projections of the scan bus electrode and the sustain bus electrode are closely located at the center of the discharge cell. Since a discharge distance can become short and a discharge firing voltage can be lowered. Therefore, since a sufficient discharge can be generated even with a low voltage, power consumption can be saved. Furthermore, the projections are included. Therefore, since a discharge can be generated over the entire area of the discharge cell, discharge efficiency and emission efficiency can be improved accordingly. Furthermore, in a manufacturing process of a plasma display apparatus, a manufacturing process can be reduced and a manufacturing time can be shortened because transparent electrodes are not formed. Therefore, the cost of the plasma display apparatus can be lowered.</p> |
