Abstract
A display device including a light emitting diode, a driving transistor, a second transistor, a third transistor, a fourth transistor, and a current blocking transistor. The current blocking transistor is a transistor of a different type from the driving transistor, and in case that a voltage of a gate electrode of the driving transistor is maintained at an initialization voltage, the current blocking transistor is turned off during a light emitting period to not transmit the light emitting current outputted by the driving transistor to an anode of the light emitting diode.
