The present invention relates to a plasma display apparatus. The plasma display apparatus according to an aspect of the present invention includes a front substrate, a first electrode, a second electrode formed on the front substrate; a rear substrate facing the front substrate; a third electrode formed in the direction intersecting with the first electrode and the second electrode on the rear substrate; wherein the first electrode and the second electrode include a transparent electrode and a bus electrode, a black layer formed on the front substrate includes a first black layer formed on the position overlapped with the barrier rib, and a second black layer formed between the transparent electrode and the bus electrode. The plasma display apparatus according to the present invention has the effect that a contrast is improved by a separate type BM structure where the first black layer is separated from the second black layer, and the reactive current is reduced by increasing a luminance and lowering the panel capacitance. Further, it has the effect that the emission of the light by a discharge is smoothly performed by controlling the width of the upper portion of the second barrier rib, and by controlling the width of the lower portion of the second barrier rib and the width of the first barrier rib according to the width of the upper portion of the second barrier rib such that a luminance can be increased and the interference of the adjacent cells can be minimized, and it has the effect that the panel capacitance generated by a barrier rib is lowered such that the reactive current is reduced. Thereby, it has the effect that the sustain period where an image is displayed can be secured relatively longer since the address time during which the scan pulse is applied is reduced.
