More Information
Summary:The present invention relates to an organic optoelectronic element comprising: an anode and cathode facing each other; a light emitting layer located between the anode and the cathode; a hole transport layer located between the anode and the light emitting layer; and a hole transport auxiliary layer located between the light emitting layer and the hole transport layer, wherein the light emitting layer comprises a first compound represented by chemical formula 1 and a second compound represented by a combination of chemical formula 2 or chemical formula 3 and chemical formula 4, and the hole transport auxiliary layer comprises a third compound represented by a combination of chemical formula 5 and chemical formula 6. Details for chemical formula 1 to chemical formula 6 are defined as in the specification. Therefore, the present invention is capable of implementing the organic optoelectronic element of low driving characteristics. 서로 마주하는 양극과 음극, 상기 양극과 상기 음극 사이에 위치하는 발광층, 상기 양극과 상기 발광층 사이에 위치하는 정공수송층, 그리고 상기 발광층과 상기 정공수송층 사이에 위치하는 정공수송보조층을 포함하고, 상기 발광층은 화학식 1로 표시되는 제1 화합물과 화학식 2 또는 화학식 3 및 화학식 4의 조합으로 표시되는 제2 화합물을 포함하고, 상기 정공수송보조층은 화학식 5 및 화학식 6의 조합으로 표시되는 제3 화합물을 포함하는 유기 광전자 소자에 관한 것이다. 상기 화학식 1 내지 화학식 6에 대한 상세 내용은 명세서에서 정의한 바와 같다.
