STACKED ORGANIC LIGHT EMITTING DIODE

摘要

In the present invention, disclosed is an organic light emitting diode comprising: an anode; a cathode; and at least two light-emitting units, which are provided between the anode and the cathode and include a light-emitting layer, wherein the light emitting unit that is closest to the cathode from among the light emitting units comprises a first n-type organic product layer, which is provided on a cathode side of the light-emitting layer, and wherein the first p-type organic product layer is provided between the light-emitting unit that is closest to the cathode from among the light-emitting units and the cathode.
