Abstract: A pixel and a display device including the pixel are disclosed. The pixel comprises a first transistor, a second transistor, a third transistor, a fourth transistor, a fifth transistor, a sixth transistor, a seventh transistor, an eighth transistor, a first capacitor, and a light emitting element. The eighth transistor includes a gate electrode configured to receive a second data voltage, a first electrode connected to a fourth node, and a second electrode configured to receive an initialization voltage. The eighth transistor adjusts a voltage level of the first capacitor based on a difference between the voltage level of the first capacitor and a level of the second data voltage.
