Abstract
A plasma display panel has heights of barrier ribs prevented from abnormally increasing at positions where a phosphor dispensing process starts and ends, improving discharge performance and uniformity of a panel. A front substrate and a rear substrate face each other. Address electrodes and display electrodes extend separately from each other in a first direction and a second direction, respectively, in a space between the front substrate and the rear substrate, the first direction crossing the second direction. Barrier ribs partition a display area including a plurality of discharge cells in the space between the front substrate and the rear substrate. A non-display area is formed along a periphery of the display area. A phosphor layer is formed in each discharge cell. The non-display area includes a buffer area formed of at least a single region outside the display area.
