Organic light emitting diode and organic light emitting device including same

Disclosed are an organic light emitting diode (OLED) and an organic light emitting device including the OLED, the organic light emitting diode (OLED) including at least one light emitting material layer (EML) disposed between two electrodes and including a first compound including a fused ring of boron and oxygen as nuclear atoms and a second compound including a fused ring of boron and oxygen as nuclear atoms, the second compound includes a condensed ring having boron and nitrogen as nuclear atoms. The first compound and the second compound may be the same luminescent material layer or adjacent luminescent material layers. The OLED can reduce its driving voltage and improve its luminous efficiency using the first compound and the second compound to simultaneously adjust their energy levels. 公开了有机发光二极管(OLED)和包括所述OLED的有机发光装置，所述有机发光二极管(OLED)包括设置在两个电极之间并且包含第一化合物和第二化合物的至少一个发光材料层(EML)，所述第一化合物包含硼和氧作为核原子的稠环，所述第二化合物包含硼和氮作为核原子的稠环。第一化合物和第二化合物可以为相同的发光材料层或相邻设置的发光材料层。使用第一化合物和第二化合物同时调节它们的能级，所述OLED可以降低其驱动电压并提高其发光效率。
