Abstract
A pixel including: a light-emitting diode; a first PMOS transistor including a first electrode connected to a node and a second electrode transmitting a driving current to the light-emitting diode; a second transistor connected between a data line and the node and turned on by a first scan signal; a third NMOS transistor connected between a gate electrode and the second electrode of the first transistor and turned on by a first emission control signal; a fourth NMOS transistor connected between the gate electrode of the first transistor and a first initialization voltage line and turned on by a second emission control signal; a fifth transistor connected between a driving voltage line and the node and turned on by the first emission control signal; and a sixth transistor connected between the second electrode of the first transistor and the light-emitting diode and turned on by the first emission control signal.
