Each of pixels arranged in a matrix comprises an element to be driven, a switching TFT, an element driving TFT, and a storage capacitor, and a potential shifting capacitor. The storage capacitor is connected between the gate and a source of the element driving TFT. Before a data signal is output, a precharge signal is output to a data line to turn on the element driving TFT, a set signal is output to a power supply line that is used to supply power through the turned-on element driving TFT to the element to be driven, and, before a data signal is applied to one electrode of the storage capacitor, the source of the element driving TFT and another electrode of the storage capacitor are discharged in response to the set signal to be fixed at a constant potential. By performing control as described above, the element to be driven is driven using a minimum number of circuit elements.
