Abstract: A plasma display panel where the address electrodes are designed to have perforated portions in the vicinity of display electrodes to prevent the build up of unwanted wall charges in the vicinity of the display electrodes to thus prevent mis-discharge in the plasma display panel. The perforations can be quadrilateral in shape, and can be made to different sizes depending on the color of the phosphor in the vicinity of the perforation. As a result, drive voltage margin quality between the different colors can be improved to produce a more reliable display.
