An nMOS is used for a drive TFT and a display device is provided without being affected by variations in the threshold voltage of the drive TFT. A display device includes: a field-effect transistor that controls a drive current of a light emitting element; a first switch provided between a source of the field-effect transistor and an anode terminal of the light emitting element; a second switch provided between the source of the field-effect transistor and a signal line; a third switch provided between a drain of the field-effect transistor and a power supply line; a fourth switch provided between the drain and a gate of the field-effect transistor; a capacitor provided between the gate of the field-effect transistor and the anode terminal of the light emitting element; and a fifth switch provided between the anode terminal of the light emitting element and a predetermined voltage supply line.
