Abstract: A pixel includes an organic light emitting diode (OLED), a first transistor, a first capacitor, a second capacitor, and a pixel circuit. The OLED includes a cathode electrode connected to a second power source. The first transistor is connected between a data line and a first node, and turns on when a scan signal is supplied to a scan line. The first capacitor is connected between the first node and a third power source. The second capacitor is connected between the first node and a fourth power source. The pixel circuit controls a current quantity flowing from a first power source to the second power source through the OLED based on a voltage of the first node.
