1. A pixel of a light-emitting display device, the pixel comprising:
a first transistor including a gate coupled to a gate node, a first terminal, and a second terminal;
a second transistor including a gate receiving a first signal, a first terminal coupled to a data line, and a second terminal coupled to the first terminal of the first transistor;
a third transistor including a gate receiving a second signal, a first terminal coupled to a line of an initialization voltage, and a second terminal coupled to an anode of a light-emitting diode; and
a fourth transistor including a gate receiving a third signal, a first terminal coupled to the second terminal of the first transistor, and a second terminal coupled to the anode of the light-emitting diode,
wherein a frequency of the first signal is different from a frequency of at least one of the second signal and the third signal.
