Organic light emitting diode and organic light emitting device having same

The present disclosure relates to an organic light-emitting diode and an organic light-emitting device having the same, and more specifically, the present disclosure relates to an organic light-emitting diode and an organic light-emitting device including the same, the organic light-emitting diode including at least two light-emitting portions each independently including a light-emitting material layer, wherein the luminescent material layers each independently comprise anthracene-based hosts having different deuterium substitution rates. Introduction of hosts having different deuterium substitution rates in the respective organic light emitting material layers enables the organic light emitting diode and the organic light emitting device to improve the light emitting efficiency and the light emitting lifetime thereof. 本公开涉及有机发光二极管和具有其的有机发光装置，更具体地，本公开涉及有机发光二极管和包括所述有机发光二极管的有机发光装置，所述有机发光二极管包括至少两个各自独立地包括发光材料层的发光部，其中发光材料层各自独立地包含具有不同氘取代率的基于蒽的主体。在各个有机发光材料层中引入有具有不同氘取代率的主体使得有机发光二极管和有机发光装置可以改善其发光效率和发光寿命。
