A pixel circuit including a first transistor, a coupling capacitor, a second transistor, and a luminescent element is provided. The first transistor is used as a switch. The coupling capacitor stores a coupling voltage and transmits the coupling voltage to the gate of the second transistor for compensating a drift of the threshold voltage of the second transistor. The second transistor provides a driving current for driving the luminescent element to emit light.
