ABSTRACT:
The present invention discloses an organic light emitting diode capable of obtaining proper luminance and long life cycle by controlling an amount of current flowing through an organic electroluminescent device per unit pixel. The organic light emitting diode includes a luminescent device and first and second transistors for driving the luminescent device, wherein the first and second transistors have different resistance values. The first transistor is a driving transistor for driving the luminescent device. The second transistor is a switching transistor for switching on and off the driving transistor. The driving transistor may have a higher resistance value than the switching transistor.
