Abstract: A display device including a pixel comprises an EVDD driving unit outputting an AC driving voltage swinging between a high potential voltage and a low potential voltage according to voltages of a first control node and a second control node, and a plurality of sub-pixels connected to a data line and a gate line to receive the AC driving voltage by sharing an output node of the EVDD driving unit. Each of the sub-pixels may include a light emitting element, a driving element for supplying a current to the light emitting element according to a gate-source voltage, a switch element turned-on according to a scan signal to connect the data line to the gate of the driving element, and a capacitor connected between a gate and a source of the driving element.
