Abstract:
A display device including a display area. The display area having a plurality of pixel circuits, a peripheral area including a scanning circuit, a plurality of first scanning lines, a plurality of second scanning lines, and a plurality of third scanning lines. Each of the plurality of pixel circuits includes a write transistor, a drive transistor, a first switching transistor, a second switching transistor, a third switching transistor, a fourth switching transistor, a capacitor, and a light emitting element. Duration of a conductive state of the third switching transistor is variably controlled by changing a width of the input pulse and duration of a conductive state of the fourth switching transistor is variably controlled by changing the width of the input pulse.
