Beschreibung
Zusammenfassung:	The present invention provides a light emitting layer ink composition for electroluminescence applicable to an inkjet printing method and a light emitting device having a light emitting layer formed from the composition. In the present invention, the light emitting layer can be formed through inkjet printing by mixing a small amount of a dispersant with a quantum dot solution to make ink, and a coffee ring phenomenon due to the addition of the dispersant can be improved. 본 발명은 잉크젯 프린팅 방식에 적용 가능한 전계 발광용 발광층 잉크 조성물 및 상기 조성물로부터 형성된 발광층을 구비하는 발광소자를 제공한다. 본 발명에서는 양자점 용액에 분산제를 소량 혼합하여 잉크화함으로써 잉크젯 프린팅을 통한 발광층 형성이 가능하게 하고, 분산제 첨가에 따른 커피링 현상을 개선할 수 있다.
