Abstract:
1. An electro-luminescent apparatus comprising: a plurality of scanning lines; a plurality of data lines; a plurality of common power supply lines; a single opposite electrode; a plurality of pixel electrodes corresponding to intersections of the plurality of scanning lines and the plurality of data lines; a plurality of first transistors each of which has a gate electrode connected to one scanning line of the plurality of scanning lines; a plurality of second transistors each of which is connected between one pixel electrode of the plurality of pixel electrodes and one common power supply line of the plurality of common power supply lines; and a plurality of luminescent elements each of which is disposed between one pixel electrode of the plurality of pixel electrodes and the single opposite electrode, the single opposite electrode overlapping the plurality of common power supply lines, and the single opposite electrode being formed for the plurality of pixel electrodes, a potential of one common power supply line of the plurality of power supply lines being higher than a potential of the single opposite electrode when one second transistor of the plurality of second transistors that is disposed between one pixel electrode of the plurality of the pixel electrodes and the one common power supply line is in an “on” state, and a potential of one pixel electrode of the plurality of pixel electrodes being higher than a potential of the single opposite electrode when one luminescent element of the plurality of luminescent elements that is disposed between the one pixel electrode and the single opposite electrode is in an “on” state.
