초록

유기 발광 다이오드(OLED)는 학문 및 산업분야에서 많은 관심을 받아 왔으며, 소자가 갖는 우수한 장점을 바탕으로 모바일 디스플레이뿐만 아니라 대면적 TV, 차세대 굴곡형 디스플레이의 적용이 활발하게 진행되고 있다. 또한 OLED 재료의 연구와 소자제작 기술의 응용 연구 범위를 넓혀가고 있다. 본 논문에서는 이러한 OLED에 대한 기본적인 소자 구성 및 원리를 설명하고, 다양한 화학구조를 응용한 OLED 재료를 각각의 용도에 맞게 분류 정리하였다. 이러한 OLED 기술의 개념과 재료의 특성을 체계적으로 분류함으로써 새로운 발광 재료를 연구하고 개발함에 있어서 많은 도움이 되리라고 생각한다.

Organic Light Emitting Diodes (OLEDs) have been receiving great attention in academic and industrial fields, and it is being actively applied to mobile display, as well as large area TV and next-generation flexible display due to their excellent advantages. In addition, the scope of research on OLED materials and device fabrication technology is getting expanded. This review discusses the principle and basic composition of OLED and also classifies OLED materials with different chemical structures according to their usages. Systematic classification of OLEDs by technical concept and material characteristics can help developing new emitting materials.

Keywords:organic light emitting diode;fluorescence;phosphorescence;hole transporting layer;electron transporting layer
