1. A pixel comprising:
an organic light-emitting diode which outputs a light based on a driving current, and includes a first terminal and a second terminal;
a driving transistor which generates the driving current, and includes:
a first terminal to which a first power supply voltage is applied;
a second terminal electrically connected to the first terminal of the organic light-emitting diode; and
a gate terminal to which an initialization voltage is applied;
a first dual gate transistor directly connected between the gate terminal of the driving transistor and the second terminal of the driving transistor, and including a first sub-transistor and a second sub-transistor, which are connected in series;
a first capacitor including a first electrode to which the first power supply voltage is applied and a second electrode directly connected to a first node which connects the first and second sub-transistors to each other; and
a compensation transistor different from the driving transistor and including a first terminal to which a compensation voltage is applied, a second terminal directly connected between the second electrode and the first node, and a gate terminal to which a compensation gate signal is applied.
