1. A pixel comprising:
a first transistor connected to a first node and having a gate electrode connected to a second node, the first node connected to a first power source;
a light emitting element having a first electrode connected to a third node and a second electrode connected to a second power source, the third node connected between the first transistor and the light emitting element;
a second transistor connected between a data line and the first node and configured to be turned on in response to a first signal enabled in a first time period;
a third transistor connected between the second node and a first initializing power line to initialize a voltage of the gate electrode of the first transistor;
a fourth transistor connected between the third node and the second node to electrically connect the third node and the gate electrode of the first transistor to each other;
a fifth transistor connected between the first node and the first power source and configured to be turned on in response to a second signal enabled in a second time period; and
a sixth transistor connected between the first electrode of the light emitting element and a second initializing power line to initialize a voltage of the first electrode;
wherein the first initializing power line has a voltage greater than a voltage of the second initializing power line, and
wherein the second time period does not overlap the first time period.
