ORGANIC LIGHT EMITTING DIODE AND ORGANIC LIGHT EMITTING DEVICE INCLUDING THE SAME

Abstract:

An organic light emitting device that includes a substrate and an organic light emitting diode positioned on the substrate is provided. The organic light emitting diode includes a first electrode, a second electrode facing the first electrode, a first emitting material layer including a first compound and positioned between the first and second electrodes, and a second emitting material layer including a second compound and positioned between the first emitting material layer and the second electrode. Each of the first and second compounds is an anthracene derivative, and a deuteration ratio of the first compound is greater than that of the second compound.
