A pixel for a display device is disclosed. In one aspect the pixel includes six transistors. For example, the pixel may includes an organic light emitting diode, a first transistor transmitting a first power source voltage to an anode of the organic light emitting diode, a second transistor transmitting a gate-on voltage to the gate electrode of the first transistor, a third transistor transmitting a gate-off voltage to the gate electrode of the first transistor according to a first control signal, a fourth transistor transmitting the gate-off voltage to the gate electrode of the second transistor according to the first control signal, a fifth transistor transmitting the second control signal to the gate electrode of the second transistor, and a sixth transistor transmitting the gate-on voltage to the gate electrode of the fifth transistor according to a third control signal. The pixels in the display are turned off for initialization and the pixels are selectively turned on to display an image.
