The present invention suppresses the generation of a leak current that accompanies the polarity inversion of the voltage waveform of the opposing electrode. The display device that performs display by sequentially scanning a plurality of scan signal lines in a single cycle period comprises: a plurality of data signal lines that intersect the scan signal lines; a pixel electrode that is connected to the data signal lines; and an opposing electrode that is disposed opposite the pixel electrode and for which the polarity of an application voltage is inverted in each of the cycle periods. The cycle period includes a scan period in which one full scan of the scan signal lines is performed and a non-scan period in which the scan signal lines are not scanned. In the non-scan period, the absolute value across the gate and drain is held at or above a predetermined value and the decrease in a voltage difference between a pixel potential and a gate OFF potential caused by the polarity inversion of the application voltage to the opposing electrode is reduced. In a non-scan period, the polarity of the voltage applied to the opposing electrode is fixed at either polarity irrespective of the polarity inversion of the voltage of the opposing electrode in each cycle period.
