Abstract
A plasma display panel. A first substrate and a second substrate are provided opposing one another with a predetermined gap therebetween. Address electrodes are formed on the second substrate. Barrier ribs are mounted between the first substrate and the second substrate defining a plurality of discharge cells. Phosphor layers are formed within the discharge cells. Discharge sustain electrodes are formed on the first substrate. 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 extending from each of the bus electrodes such that a pair of opposing protrusion electrodes is formed within an area corresponding to each discharge cell. A distal end of each protrusion electrode includes an indentation such that a gap is formed between the pair of opposing protrusion electrodes, and an aperture is formed in each protrusion electrode.
