1. A pixel circuit, comprising:
a driving transistor including a gate electrode, a first electrode, and a second electrode;
a capacitor connected to the gate electrode;
a first transistor connected to the gate electrode and the second electrode;
a second transistor which is connected to the first transistor and is configured to receive an initialization voltage;
a third transistor which is connected to the capacitor and is configured to receive the initialization voltage;
a fourth transistor connected to the first transistor and the second electrode;
a fifth transistor connected to the first transistor, the third transistor, and the fourth transistor; and
a light emitting diode connected to the fourth transistor and the fifth transistor,
wherein, during one frame, each of a turn-on period of the second transistor and a turn-on period of the third transistor does not overlap with a turn-off period of the fourth transistor.
