PLASMA DISPLAY PANEL HAVING DISCHARGE MAINTAINING ELECTRODE WITH DOUBLE GAP, AND MANUFACTURING METHOD OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a plasma display panel having a discharge maintaining electrode with double gap, and provide a manufacturing method of the same. SOLUTION: The plasma display panel is provided with the discharge sustaining electrode formed from a double gap structure having a prescribed resistance. The discharge sustaining electrode is composed of main electrodes for main discharge and auxiliary electrodes for initiating low voltage discharge without lowering the efficiency, and the distance between the auxiliary electrodes is made narrower than the distance between the main electrodes. The auxiliary electrodes are located between separation walls or at the position corresponding to just upper side of the separation walls. A ditch or a groove is formed on the discharge maintaining electrodes and a dielectric layer covering the auxiliary electrodes. The groove is formed at just upper side of the auxiliary electrodes. By utilizing this invention, a discharge voltage is sharply reduced comparing to a conventional PDP while maintaining the gas pressure of the plasma formation gas used for the PDP as high as that of a conventional PDP.
