A plasma display apparatus is disclosed. The plasma display apparatus includes a plasma display panel including a scan electrode, a sustain voltage supply unit supplying a sustain voltage to the scan electrode, a scan reference voltage supply unit supplying a scan reference voltage to the scan electrode, a scan reference voltage controller that is connected between the scan reference voltage supply unit and the scan electrode and includes a resistor changing the scan reference voltage into a reset signal with a predetermined slope, a voltage storing unit that is connected between the sustain voltage supply unit and the scan reference voltage supply unit and stores the scan reference voltage, and a driving signal output unit that controls an output of a voltage supplied to the scan electrode using a single switch.
