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.

Abstract: An organic light emitting diode and an organic light emitting device containing the same are provided. The organic light emitting diode includes at least two emitting parts each of which includes independently an emitting material layer. Each of the emitting material layers includes independently an anthracene-based host having different deuterium substitution rates. The organic light emitting device includes the organic light emitting diode. Hosts with different deuterium substitution rates are introduced into each organic emitting material layer to improve luminous efficiency and luminous lifespan of the organic light emitting diode and the organic light emitting device.
