Abstract: 본 발명은 유기발광전자소자에 관한 것으로, 나노 구조체를 형성시킨 기판을 유기 발광 전자 소자에 적용하기 위해 기판을 효과적으로 평탄화하는 방법에 관한 것이다. 본 발명은 기판, 상기 기판 상에 형성된 주기성 또는 비주기성을 갖는 요철 형상의 미세 패턴을 갖는 나노 구조체, 상기 나노 구조체 위에 형성된 평탄화층, 상기 평탄화층 위에 형성된 제 1 전극, 상기 제 1 전극 위에 형성된 유기물층, 및 상기 유기물층 위에 형성된 제 2 전극을 포함하는 유기발광소자의 제조방법에 있어서, 평탄화층이 평탄화판에 의해 4~6bar로 가압되어 평탄화되는 것을 특징으로 하는 유기발광소자의 제조방법을 제공한다. 본 발명에서는 미쇄패턴을 갖는 나노구조체를 평탄화를 함으로써 미세 패턴의 모서리에 의해 발생하는 누설전류를 최소화하여 이로 인해 발생하는 효율감소를 막고 전반사와 광 도파로 모드로 인해 손실되는 광을 기판 외부로 추출함으로써 외부 양자 효율이 향상된 유기 발광 소자를 실현할 수 있다.
