A plasma display panel includes first and second substrates facing each other and divided into a display area and a non-display area, barrier ribs disposed between the first and second substrates, the barrier ribs defining a display discharge cell in the display area and a non-display discharge cell in the non-display area, a sustain electrode disposed between the first and second substrates, an address electrode disposed between the first and second substrates, the address electrode being perpendicular to the sustain electrode, the address electrode including a first dummy address electrode that protrudes on at least one end from an outermost barrier rib in the non-display region, and a composite layer covering the address electrode including at least a part of the first dummy address electrode. The composite layer may be formed of the same material as and may be a single body with the barrier ribs.
