Zusammenfassung:	The present invention relates to a polycyclic aromatic derivative and an electroluminescent device comprising same. The electroluminescent device according to the present invention comprises a polycyclic aromatic derivative as a dopant compound in a light-emitting layer thereof and also employs an anthracene derivative having a characteristic structure, as a host in combination therewith, in the light-emitting layer, whereby the electroluminescent device can have excellent color purity, high light-emitting efficiency, and a remarkably improved long lifespan, and thus can be advantageously used in various display devices. La présente invention concerne un dérivé aromatique polycyclique et un dispositif électroluminescent le comprenant. Le dispositif électroluminescent selon la présente invention comprend un dérivé aromatique polycyclique en tant que composé dopant dans une couche électroluminescente de celui-ci et utilise également un dérivé d'anthracène ayant une structure caractéristique, en tant qu'hôte en combinaison avec celle-ci, dans la couche électroluminescente, le dispositif électroluminescent pouvant présenter une excellente pureté de couleur, une efficacité d'émission de lumière élevée, et une durée de vie remarquablement prolongée, et pouvant ainsi être utilisé avantageusement dans divers dispositifs d'affichage. 본 발명은 다환 방향족 유도체 화합물 및 이를 포함하는 유기발광소자에 관한 것으로서, 본 발명에 따른 유기발광소자는 다환 방향족 유도체 화합물을 발광층에 도펀트 화합물로 포함하고, 또한, 이와 함께 특징적 구조의 안트라센 유도체 화합물을 호스트로 조합하여 발광층에 함께 채용함으로서 우수한 색순도, 높은 발광 효율 및 현저히 향상된 장수명을 가져서 다양한 디스플레이 소자에 유용하게 활용할 수 있다.
