    Abstract: A display device includes: a plurality of pixels, each of the pixels including: a switching transistor; a relay transistor; a first capacitor; a driving transistor; and an organic light emitting diode (OLED). The OLED emits light according to a driving current from a first power source voltage, and a light emitting period for the OLED is one of a first light emitting period that is not temporally overlapped with a scan period in which data are written to the pixels or a second light emitting period that is temporally overlapped with the scan period. A duty of the light emitting period is controlled by controlling a time when a second power source voltage is applied as a low level voltage within the first light emitting period or controlling a time when the second power source voltage is applied as a low level voltage within the second light emitting period.
