1. A pixel circuit comprising:
a light emitting element including a first electrode and a second electrode;
a first switching element which applies a first power voltage to the first electrode of the light emitting element and includes a control electrode;
a second switching element which applies a data voltage to the control electrode of the first switching element;
a third switching element which senses a signal of the first electrode of the light emitting element;
a sensing resistor including a first end connected to the second electrode of the light emitting element and a second end which receives a second power voltage; and
a fourth switching element which senses a signal of the second electrode of the light emitting element and connected to the first end of the sensing resistor.
