A plasma display apparatus is provided. The plasma display apparatus includes an upper substrate, a lower substrate that faces the upper substrate, and barrier ribs formed on the lower substrate to partition off discharge cells. At least one groove having a width no less than 0.1 times and no more than 0.8 times the width of the barrier rib is formed on the barrier rib. Therefore, it is possible to reduce a capacitance value between address electrodes and reduce reactive power formed between the electrodes so that it is possible to improve the discharge efficiency of the panel.
