Abstract:
1. A driving method of a display device comprising a wire and a plurality of pixels each of which includes a first transistor, a second transistor, a light-emitting element including a pair of electrodes, and a capacitor including a pair of electrodes, wherein the wire is electrically connected to one of a source electrode and a drain electrode of the first transistor, wherein the other of the source electrode and the drain electrode of the first transistor is electrically connected to one electrode of the light-emitting element, and to one of a source electrode and a drain electrode of the second transistor, wherein the other of the source electrode and the drain electrode of the second transistor is electrically connected to the other electrode of the light-emitting element, wherein gate electrodes of the first and second transistors are electrically connected to one electrode of the capacitor, and wherein the other electrode of the capacitor is electrically connected to the wire, and the driving method comprising: setting a potential difference between the pair of electrodes of the light-emitting element to be lower than a threshold voltage of the light-emitting element so that the light-emitting element emits no light by turning the second transistor on in the case where the source electrode and the drain electrode of the first transistor is short-circuited and a potential of the wire is applied to the one electrode of the light-emitting element.
