摘要： A display device includes a plurality of pixel circuits each including: a light-emitting element; a pulse width modulation (PWM) controller configured to control whether to supply current to the light-emitting element; and a constant current controller configured to supply the current to the light-emitting element, wherein the constant current controller, the PWM controller, and the light-emitting element are connected in series between a first power line and a second power line to supply the current to the light-emitting element; and a transistor configured to turn off the light-emitting element during a constant current setting period is provided between the first power line and the constant current controller.
