<p>For a first period, a TFT (Q1) is turned ON, and a TFT (Q2) is turned OFF. Moreover, a potential (Va) is fed to a source wiring (Sj) to set the potential of a pixel electrode (14) to Va. For a second period, the TFT (Q1) is turned OFF, and the TFT (Q2) is turned ON. At this time, too, the potential (Va) is continuously fed to the source wiring (Sj). As a result, the potential of a node (15) is set to Va, and the potential of the pixel electrode (14) is varied. For a third period, both the TFTs (Q1 and Q2) are turned OFF. This constitution realizes a display device, which can make such a magnitude difference of the effective value of a voltage expressed by the difference between a potential to be applied to the drive potential input terminal of an electrooptic element and a reference potential, larger than the amplitudes of signal voltages to be outputted to a data signal line, as corresponds to the difference in the signal voltages, while suppressing the factors for a high cost and the increase in a power consumption.</p> |
