Abstract: A plasma display panel minimizing the presence of electrodes outside the display area. In forming the display electrodes across the display, the electrodes extend to only one of the right or left side of the display area. In forming the address electrodes, the electrodes extend to only one of a top or a bottom side of the display area. By so limiting the amount of electrodes outside the display area, less electrode paste is consumed thus reducing expenses and the size of the glass substrate is reduced thus resulting in a more compact display. All of this can be achieved without reducing the display area of the display.
