Abstract: An EL (Electro Luminescence) display device controlling luminosity by a current value supplied to a light emitting element. The EL display device includes a power source supplying a current to the light emitting element and includes a first variable power source and a second variable power source outputting a lower potential than the first variable power source, and a control part changing an output potential of the first variable power source and an output potential of the second variable power source according to acquired maximum luminosity data. Furthermore, the EL display device includes a gate signal output part and a data signal output part, and the control part may change a power source potential of the gate signal output part or a power source potential of the data signal output part according to the maximum luminosity data.

Abstract: A display device includes a liquid crystal display panel, two electrodes in the liquid crystal display panel, a switching element having a source and a drain one of which is coupled to one of the two electrodes, a scan line coupled to a gate of the switching element, a signal line coupled to the other of the drain and the source, an inversion driver, and a scan circuit configured to provide, to the scan line, any of a first potential, a second potential, and a third potential lower than the second potential. The scan circuit switches a potential of the scan line from the second potential to the third potential at a timing at which the potential of the other of the two electrodes is made lower than that of the one of the two electrodes in a period in which the source and the drain are electrically disconnected.
