A Plasma Display Panel (PDP) capable of reducing an address discharge voltage between address electrodes and Y electrodes, suppressing an address discharge delay, and improving brightness includes: a first substrate, a second substrate spaced apart from the first substrate and facing the first substrate, barrier ribs arranged between the first and second substrates and defining discharge cells where a discharge occurs, discharge electrode pairs including X electrodes and Y electrodes extending across the discharge cells, floating electrodes arranged closer to the Y electrodes than to the X electrodes, address electrodes extending across the discharge cells and intersecting the discharge electrode pairs within the discharge cells, and phosphor layers arranged within the discharge cells. Portions of the address electrodes facing the Y electrodes are wider than portions of the address electrodes facing the X electrodes, or distances between the Y electrodes and the portions of the address electrodes facing the Y electrodes are shorter than distances between the X electrodes and the portions of the address electrodes facing the X electrodes.

A plasma display panel with reinforcing electrodes arranged at both ends of discharge cells along a direction address electrodes are formed and coupled to display electrodes. The reinforcing electrodes may comprise carbon-based material such as carbon nanotubes or graphite, and they may be stacked in two or more layers and covered with a dielectric layer and a protective layer. The dielectric layer may be interposed between the reinforcing electrodes and the display electrodes. The dielectric layer may expose the reinforcing electrodes so that the protective layer covers the reinforcing electrodes. A portion of the protective layer corresponding to the reinforcing electrodes has a surface roughness of about 300 nm to about 700 nm.
