In accordance with the present invention, disclosed is an organic electroluminescent device. The corresponding organic electroluminescent device includes a cathode, an anode, and an organic layer disposed therebetween; the organic layer includes a first organic layer, the first organic layer includes a first compound and a second compound; the first compound has a structure having specified HOMO and/or LUMO energy levels and represented by Formula 1-1; and the second compound has a structure having a specified LUMO energy level and represented by Formula 2-1. As a combination of the first compound and the second compound is selected, the performance of the organic electroluminescent device such as the efficiency of the device can be significantly improved. Also, disclosed is an electronic facility including the corresponding organic electroluminescent device.

    본 발명은 유기 전계발광소자를 개시하였다. 해당 유기 전계발광소자는 음극, 양극, 및 양자 사이에 배치된 유기층을 포함하며; 상기 유기층은 제1 유기층을 포함하고, 상기 제1 유기층은 제1 화합물과 제2 화합물을 포함하며; 상기 제1 화합물은 특정된 HOMO 및/또는 LUMO 에너지 준위를 갖고 식 1-1로 나타내는 구조를 구비하고; 상기 제2 화합물은 특정된 LUMO 에너지 준위를 갖고 식 2-1로 나타내는 구조를 구비한다. 제1 화합물과 제2 화합물의 조합을 선택함으로써, 기존 기술에 비해, 유기 전계발광소자의 성능, 예를 들어 소자의 효율 등을 현저하게 향상시킬 수 있다. 또한 해당 유기 전계발광소자를 포함하는 전자 설비를 더 개시하였다.
