Zusammenfassung:	The present invention provides a light-emitting layer ink composition for electroluminescence which can be applied to an inkjet printing method, and a light-emitting device comprising a light-emitting layer formed from the composition. According to the present invention, a small amount of dispersant is mixed with a quantum dot solution, and the mixture is converted into ink, so as to enable formation of a light-emitting layer by means of inkjet printing and ameliorate a coffee ring effect caused by an addition of the dispersant. La présente invention concerne une composition d'encre à couche électroluminescente pour une électroluminescence qui peut être appliquée à un procédé d'impression à jet d'encre, et un dispositif électroluminescent comprenant une couche électroluminescente formée à partir de la composition. Selon la présente invention, une petite quantité de dispersant est mélangée avec une solution de points quantiques, et le mélange est converti en encre, de façon à permettre la formation d'une couche électroluminescente au moyen d'une impression à jet d'encre et à améliorer un effet de cycle de café provoqué par une addition du dispersant. 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.
