    • 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.
    • 本发明抑制伴随着相对电极的电压波形的极性反转的漏电流的产生。 通过在单个周期中顺序扫描多条扫描信号线进行显示的显示装置包括:与扫描信号线相交的多条数据信号线; 连接到数据信号线的像素电极; 以及与像素电极相对设置并且在每个循环周期中施加电压的极性反转的对置电极。 循环周期包括其中执行扫描信号线的一次全扫描和不扫描扫描信号线的非扫描周期的扫描周期。 在非扫描周期中,栅极和漏极两端的绝对值保持在预定值以上,并且由施加电压的极性反转引起的像素电位与栅极截止电位之间的电压差的降低 相对电极减少。 在非扫描周期中,施加到对置电极的电压的极性固定为任一极性,而与每个周期中相对电极的电压的极性反转无关。
