There is provided a display device that compensates, without being equipped with a frame memory, change in the capacitance value of an electro-optical element, such as a liquid crystal or the like, occurring with change in the voltage applied to the electro-optical element. The response speed of the display device is also improved. For each of pixel formation portions (A1j, A2j), a frame period is divided into a first period and a second period. In the frame period, a target voltage is applied to the pixel formation portions (A1j, A2j), the target voltage being a voltage having either one of positive and negative polarities relative to the voltage level (Com) of an opposing electrode. In the first period of the frame period, a TFT is brought into a conductive state and a voltage corresponding to the target voltage is applied to a source line (Sj), thereby applying, to a pixel electrode of the pixel formation portions (A1j, A2j), a voltage having the another polarity relative to the voltage level (Com) of the opposing electrode. In the second period of the frame period, the TFT is brought into a non-conductive state and the voltage of an auxiliary capacitor wiring (Ck) is changed from the another polarity to the one polarity relative to the voltage level of the opposing electrode, thereby applying the target voltage to the pixel formation portions (A1j, A2j).
