More Information
Summary:The present invention relates to an organic electroluminescent device comprising: an anode; a light emitting layer; a first hole transport layer which is disposed between the anode and the light emitting layer, and includes an electron accepting material; and a second hole transport layer which is disposed between the first hole transport layer and the light emitting layer, and includes a hole transport material represented by chemical formula 1. The organic electroluminescent device shows improved light emitting efficiency and light emitting lifespan. 일 실시예의 유기 전계 발광 소자는 애노드; 발광층; 상기 애노드와 상기 발광층 사이에 배치되고, 전자 수용 재료를 포함하는 제 1 정공 수송층; 및 상기 제 1 정공 수송층과 상기 발광층 사이에 배치고, 하기의 일반식 (1)로 표시되는 정공 수송 재료를 포함하는 제 2 정공 수송층; 을 포함하여 개선된 발광 효율 및 발광 수명을 나타낼 수 있다.
