Abstract:
In an active matrix type display apparatus, 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 first current capable of conducting the drive transistor. The first current does not correspond to a signal current corresponding to a current injected to the display element. 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 second current. The second current corresponds to a signal current corresponding to the current injected to the display element. 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.
