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.
