Abstract
A plasma display panel is provided which reduces power consumption requirements and improves discharge efficiency. Transparent electrodes are formed so as to extend to a center portion of neighboring discharge cells, and perpendicular to projection electrodes formed along the barrier ribs to enhance discharge efficiency. A pair of wings formed on the ends of the transparent electrodes further improves discharge efficiency, while scan and projection electrodes are formed along a portion of the barrier ribs to enhance brightness.
