Claim:
A display device comprising: a pixel array including pixel circuits arranged in a matrix state, in which each pixel circuit has at least: a light emitting element, a drive transistor that has a first current electrode connected to a current path connected to the light emitting element and is configured to supply electric current to the light emitting element, the magnitude of the electric current supplied to the light emitting element depending on a gate-source voltage between a gate electrode of the drive transistor and the first current electrode of the drive transistor, and a storage capacitor connected between the gate electrode of the drive transistor and the first current electrode of the drive transistor and that is configured to store a threshold voltage of the drive transistor and an inputted signal value; and a driving circuit configured to: selectively apply a signal potential and a reference potential to the gate electrode of the drive transistor of each pixel circuit and to the storage capacitor of each pixel circuit, selectively apply a drive voltage to a second current electrode of the drive transistor of each pixel circuit, and perform a threshold correction operation for a given one of the pixel circuits during a plurality of threshold correction periods, wherein the plurality of threshold correction periods occur during a frame period before the signal potential is applied to the storage capacitor of the given one of the pixel circuits, and wherein the threshold correction operation causes the storage capacitor of the given one of the pixel circuits to store the threshold voltage of the drive transistor of the given one of the pixel circuits and comprises applying the drive voltage to the drive transistor of the given one of the pixel circuits while the reference potential is applied to the gate electrode of the drive transistor of the given one of the pixel circuits; wherein there are a plurality of after-correction periods during the frame period, each of the plurality of after-correction periods beginning after one of the plurality of threshold correction periods ends and before a next one of the plurality of threshold correction periods starts, and wherein the driving circuit is further configured to: place the drive transistor of the given one of the pixel circuits in a cut-off state during at least one of the plurality of after-correction periods prior to the threshold voltage of the drive transistor of the given one of the pixel circuits being stored in the storage capacitor of the given one of the pixel circuits, the cut-off state corresponding to a state in which a current does not flow through the drive transistor of the given one of the pixel circuits, and not place the drive transistor of the given one of the pixel circuits in the cut-off state during at least one of the plurality of after-correction periods.
