Beschreibung
Zusammenfassung:	The present invention provides an organic electroluminescent element which simultaneously exhibits high luminous efficiency, low driving voltage, long lifespan and the like by having an organic functional layer having a refractive index equal to or higher than the refractive index of the light emitting layer between the light emitting layer and an electron transport region. 본 발명은 발광층과 전자 수송 영역 사이에, 당해 발광층의 굴절률과 같거나 높은 굴절률을 갖는 유기 기능층을 구비하여 높은 발광효율, 낮은 구동전압 및 장수명 등을 동시에 발휘하는 유기 전계 발광 소자를 제공할 수 있다.
