To provide a light emitting display device including pixel circuits capable of compensating the threshold voltage of a driving transistor.
In each pixel circuit of the light emitting display device, one electrode of a capacitor is connected to the gate of a first transistor. A first switching element switches the driving transistor to a diode connection state in response to the first level of a first control signal. A second switching element supplies a current output from the first main electrode of the driving transistor to the light emitting element in response to the second level of a second control signal. The light emitting element emits light in response to the current from the second switching element. In the on state of the first switching element, the second switching element is turned on in a first period, and after the first period, the second switching element is turned off. In the off state of the first switching element, the second switching element is turned on. The first period is preferably longer than 0.05μs and shorter than 2.5μs.
