Abstract: A pixel includes an organic light-emitting diode, a driving transistor, a first dual gate transistor, a first capacitor, and a compensation transistor. The organic light-emitting diode includes first and second terminals. The driving transistor generates the driving current and includes a first terminal to which a first power supply voltage is applied, a second terminal connected to the first terminal of the organic light-emitting diode, and a gate terminal. The first dual gate transistor is connected between the gate terminal of the driving transistor and the second terminal of the driving transistor and includes first and second sub-transistors. The first capacitor includes a first electrode to which the first power supply voltage is applied, and a second electrode connected to a first node that connects the first and second sub-transistors to each other. The compensation transistor includes a terminal connected between the second electrode and the first node.
