Abstract
In a plasma display panel, a scanning electrode and a common electrode are alternately formed in strips and parallel to one another on a lower surface of a front substrate. A bus electrode is formed on lower surfaces of the respective scanning and common electrodes to have a narrower width than that of each of the scanning and common electrodes. A black matrix layer is formed of the same insulative material to be parallel to the electrodes at a boundary area between neighboring discharge cells, in which each cell is constituted by a discharge space including a pair of the scanning electrode and the common electrode, and between the scanning and common electrodes and the bus electrode, on a lower surface of the front substrate.
