The present invention relates to a plasma display panel with barrier ribs configured in a closed shape. The panel has sub-pixel cells each with a cell area that is defined by the closed shape barrier ribs, sustain electrodes each spaced apart in a row direction at a predetermined cell length, and data electrodes each overlapping a barrier rib wall in a column direction and extending under the cell area. A plurality of the sub-pixels cells in a delta configuration defines a color pixel, whereby a dual scan gap of a predetermined gap length is formed between a pair of the data electrodes in the column direction, and a gap is formed between the row barrier ribs and data electrodes.
