Abstract: A plasma display panel includes first and second substrates opposing one another. Address electrodes are formed on the first substrate in a first direction. Barrier ribs are mounted between the first and second substrates defining non-discharge regions and discharge cells, and phosphor layers are formed within the discharge cells. Discharge sustain electrodes are formed on the second substrate in a second direction substantially perpendicular to the first direction. The non-discharge regions are formed in areas encompassed by discharge cell abscissas and ordinates that pass through centers of adjacent discharge cells. The discharge sustain electrodes include bus electrodes that extend such that a pair of the bus electrodes is provided for each of the discharge cells, and protrusion electrodes formed extending from each of the bus electrodes such that a pair of opposing protrusion electrodes is formed in each discharge cell.

Illustratively, a plasma display panel may include first and second substrates provided with a predetermined gap therebetween. Address electrodes are formed on the first substrate, and a first dielectric layer is formed covering the address electrodes. Barrier ribs are formed on the first dielectric layer to a predetermined height to thereby define discharge cells, and phosphor layers are formed within the discharge cells. Discharge sustain electrodes are formed on the second substrate in a state substantially perpendicular to the address electrodes. A second dielectric layer is formed covering the discharge sustain electrodes. A protection layer is formed coating the second dielectric layer, the protection layer including MgO. The discharge cells and/or the protection layer include a Gd group compound. During use, the Gd group compound produces an enhanced illumination of blue phosphors.
