In a plasma display device, a source of a first transistor S1 is coupled to an X electrode, and a drain thereof is coupled to a cathode of a diode D1. An anode of the diode D1 is coupled to a first power source for supplying a first voltage V1. A drain of the first transistor S1 is coupled to a drain of a second transistor S2 through a capacitor, and a source of the second transistor S2 is coupled to a ground source for supplying a second voltage of 0 V. A third transistor S3 has a source coupled to the drain of the second transistor S2 and a drain coupled to a third power source for supplying a third voltage V2, and a fourth transistor S4 has a drain coupled to the X electrode and a source coupled to the drain of the second transistor S2.
