Abstract

본 발명은 p-doping과 정공수송 및 정공주입 기능을 함께 거둘 수 있는 융합된 구조의 다기능 정공수송 재료 화합물을 이용하여 정공 관련 기능층을 다기능 단일 정공층으로 구성하여 저전압 구동 및 고효율을 거둘 수 있는 유기발광소자에 관한 것으로서, 본 발명에 따르면 유기발광소자의 제조 공정 효율성도 향상시키면서 기존 구조와 동등한 수준 또는 그 이상의 저전압 구동 고효율 특성을 구현할 수 있으며, 정공층이 정공수송 재료로서 원하는 전기전도도 물성과 전압강하 효과까지 거둠과 동시에 단일 정공층 두께를 1,000 Å까지도 할 수 있어 정공층의 기계적 물성도 향상시킬 수 있다.
