ABSTRACT:
An image display apparatus includes a display unit and a voltage source, with the display unit having display devices and pixel circuits. Each of the pixel circuits is provided with a drive transistor which has a first primary electrode connected to one terminal of each of the display devices, a second primary electrode connected to a first common electrode, and a control electrode for controlling by an electric potential the magnitude of a drive current supplied to the display devices. In addition, and a control transistor has a source electrode and a drain electrode connected to the control electrode and the first primary electrode, respectively, and a gate electrode to which a signal switching between an on-state and an off-state is supplied, with an electric potential of the control electrode being set up at the on-state. The voltage source can adjust a voltage applied between the first common electrode and a second common electrode with another terminal of the display device being connected thereto.
