A display apparatus (10) comprises a scan drive circuit (74) that applies a scan voltage to display electrodes (2,Y1-Yn) during a first interval and also applies a sustain voltage pulse to the display electrodes (2,Y1-Yn) during a second interval; a sustain voltage circuit (64) that applies sustain voltage pulse potentials to two input terminals of the scan drive circuit via two signal lines (SU,SD) during the second interval; a short-circuiting switch (SW1) that short-circuits the two input terminals of the scan drive circuit during the second interval; and a switch control circuit (604) that activates the short-circuiting switch. The switch control circuit provides a control signal (SW_CTRL) for activating the short-circuiting switch so as to short-circuit the two input terminals during the second interval. |
