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