During a first selection period, a second main conductive terminal of a drive transistor and a display element are isolated, and at the same time, a control terminal of the drive transistor and the second main conductive terminal and a signal line are connected, and the signal line is supplied with a constant current capable of conducting the drive transistor, and during a second selection period, a connection of the second main conductive terminal of the drive transistor and the signal line is broken, and the signal line is supplied with a signal current corresponding to a current injected to the display element, and during a non-selection period, the second main conductive terminal of the drive transistor and the display element are connected, and the drive current of the drive transistor corresponding to voltage between both terminals of a capacitive element is supplied to the display element.
