Provided is an organic electroluminescence device. The organic electroluminescence device according to an embodiment includes a first electrode, a second electrode facing the first electrode, and a plurality of organic layers between the first electrode and the second electrode, wherein at least one of the plurality of organic layers includes an organometallic complex including a metal atom which is a central atom, a plurality of ligand connected to the metal atom, and a nitrogen atom connecting two of the plurality of ligands. The nitrogen atom includes an aromatic ring group as a substituent. The aromatic ring group is not bonded to any of the plurality of ligands to form a ring, thereby allowing the organic electroluminescent device to exhibit a low drive voltage and improved life time.
提供的是一种有机电致发光器件。根据一种实施例,该有机电致发光器件包括第一电极、朝向第一电极的第二电极,以及位于第一电极和第二电极之间的多个有机层,其中多个有机层中至少有一个包括一种含有
金属原子作为中心原子的有机
金属配合物,多个
配体连接到
金属原子,以及一个氮原子连接两个多个
配体。氮原子包括芳香环基作为取代基。该芳香环基未与多个
配体中的任何一个结合形成环,从而使得有机电致发光器件能够表现出低驱动电压和改善的寿命。
