Abstract
본 발명은 양극/정공 주입층/정공 수송층/발광층/전자 수송층/전자 주입층/음극으로 구성되는 일반적인 유기전계발광소자에 있어서, 정공 주입층 및 정공 수송층의 물질이 하기의 화학식 1로 나타내어지는 유기전계발광소자에 관한 것이다.
화학식 1
Description
유기전계발광소자는 전자 주입 전극(음극)과 정공 주입 전극(양극) 사이에 형성된 유기막에 전하를 주입하면 전자와 정공이 쌍을 이룬 후 소멸하면서 빛을 내는 소자이다. 플라스틱 같은 휠 수 있는(flexible) 투명 기판 위에도 소자를 형성할 수 있을 뿐 아니라, 플라즈마 디스플레이 패널(Plasma Display Panel)이나 무기 전계 발광(EL) 디스플레이에 비해 낮은 전압에서(10V이하) 구동이 가능하고, 또한 전력 소모가 비교적 적으며, 색감이 뛰어나다는 장점이 있다. 또한 유기 전계 발광(EL) 소자는 녹색, 청색, 적색의 3가지 색을 나타낼 수가 있어 차세대 풍부한 색 디스플레이 소자로 많은 사람들의 많은 관심의 대상이 되고 있다. 여기서 유기 EL 소자를 제작하는 과정을 간단히 살펴보면,
(1) 먼저, 투명기판 위에 양극 물질을 입힌다. 양극 물질로는 흔히 ITO(indium tin oxide)가 쓰인다.
(2) 그 위에 정공주입층(HIL:hole injecting layer)을 입힌다. 정공주입층으로는 주로 구리 프탈로시아닌(copper phthalocyanine(CuPc))을 10nm 내지 30nm 두께로 입힌다.
(3) 그런 다음 정공수송층(HTL:hole transport layer)을 도입한다. 이러한 정공수송층으로는 4,4'-비스[N-(1-나프틸)-N-페닐아미노]바이페닐(4,4'-bis[N-(1-naphthyl)-N-phenthylamino]-biphenyl(NPB)을 30nm 내지 60nm 정도 증착하여 입힌다.
(4) 그 위에 유기발광층(organic emitting layer)을 형성한다. 이때 필요에 따라 불순물(dopant)을 첨가한다. 녹색(green) 발광의 경우 흔히 유기발광층으로 트리스(8-하이드록시퀴놀레이트)알루미늄(Alq3)(tris(8-hydroxy-quinolatealuminum)을 두께 30~60nm 정도 증착하며 불순물(dopant)로는 MQD(N-메틸퀴나크리돈)(N-Meth ylquinacridone)를 많이 쓴다.
(5) 그 위에 전자수송층(ETL:electron transport layer) 및 전자주입층(EI L: electron injecting layer)을 연속적으로 입히거나, 아니면 전자주입운송층을 형성한다. 녹색(green) 발광의 경우 상기(4)의 Alq3가 좋은 전자수송능력을 갖기 때문에 전자 주입/수송층을 쓰지 않는 경우도 많다.
(6) 다음 음극(cathode)을 입히고, 마지막으로 보호막을 덧 씌우게 된다.
상기와 같은 구조에 있어 정공 주입 및 수송층을 어떻게 형성하느냐에 발광 소자에 있어 고효율 장수명의 소자를 구현 할 수가 있다. 그리하여 새로운 정공 주입 및 수송물질이 절실히 필요하다.
따라서, 본 발명은 정공 주입층 및 수송층으로 하기의 화학식 1의 물질을 사용하는 고휘도 유기전계발광소자를 구현하는데 그 목적이 있다.
