A pixel circuit is disclosed. The pixel circuit includes first and second capacitors, and a driving transistor, which generates a driving current. The pixel circuit includes a first transistor, controlled by a first driving signal, and which transmits a data signal to the first capacitor. The pixel circuit includes a second transistor, controlled by a second driving signal, and which transmits the data signal to the driving transistor. The pixel circuit includes a third transistor, controlled by the first driving signal, and which transmits a reference signal to the driving transistor. The pixel circuit includes a fourth transistor, controlled by a third driving signal, and which transmits the driving current to the light emitting element. The first capacitor stores the data signal and stabilizes the voltage between the gate and the source of the driving transistor, and the second capacitor stabilizes a source voltage of the driving transistor.
