A pixel circuit of a light-emitting display that reduces the influence of kickback generated by parasitic capacitance. The pixel circuit includes first to fourth transistors, a capacitor, and a light-emitting element. The first and second transistors are serially coupled to each other and turned on in response to a first control signal. The capacitor is coupled in parallel with the first and second transistors. The third transistor supplies a data voltage to a first electrode of the capacitor in response to a select signal. The fourth transistor outputs a current corresponding to its gate-source voltage, which is based on the voltage of the capacitor. The light-emitting element emits light corresponding to the current from the fourth transistor.
