Abstract
An organic light emitting diode that uses edge light emission and has a long lifespan. An anode and a cathode are spaced by a pattern distance and they are located at the upper and lower portions of the light emitting part respectively. The organic light emitting diode uses a separate light emission area of the light emitting part for each of the initial and the final usage stages so that a tail drop of the luminance is prevented and the lifespan of the diode is increased.
