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.
