A pixel and an organic light emitting device that can display an image having a desired luminance. The pixel includes an organic light emitting diode (OLED), first through third transistors, and a first capacitor. The OLED has a cathode electrode coupled to a second power source. The second transistor controls the current from a first power source to the OLED. The first capacitor has a first terminal coupled to a gate electrode of the second transistor. The first transistor is coupled between a second terminal of the first capacitor and a data line, and turns on when a scan signal is supplied to a scan line. The third transistor is coupled between the gate electrode and a second electrode of the second transistor, and turns on when a control signal is supplied to a control line. The third transistor remains turned on for a longer time than the first transistor. |
