Abstract
An electrode drive circuit of a plasma display device comprises: a scan driver provided with plural drivers including first and second switching elements and first and second diodes; a capacitor connected between the high potential side terminal and the low potential side terminal of the scan driver; a voltage supply circuit for selectively supplying plural voltages relating to the positive and negative voltages of the reset pulse and the voltage of a scan pulse to the low potential side terminal of the second switching element; and a negative reset switch and a resistor connected in series between the high potential side terminal of the first switching element and a ground terminal, wherein the reset pulse of negative polarity is applied by turning on the negative reset switch in a state where the capacitor is charged with the negative voltage of the reset pulse.
