Provided are a light-emitting diode solvent, a light-emitting diode ink comprising same, and a method for manufacturing a display. A light-emitting diode ink comprises a light-emitting diode solvent and light-emitting diodes which are dispersed in the light-emitting diode solvent and each comprise multiple semiconductor layers and an insulative film surrounding the outer surface of the semiconductor layers, wherein the light-emitting diode solvent is an organic solvent having a pKa ranging from 7 to 15. L'invention concerne un solvant pour diodes électroluminescentes, une encre pour diodes électroluminescentes le comprenant et un procédé de fabrication d'un dispositif d'affichage. Une encre pour diodes électroluminescentes comprend un solvant pour diodes électroluminescentes et des diodes électroluminescentes qui sont dispersées dans le solvant pour diodes électroluminescentes et qui comprennent chacune de multiples couches semi-conductrices et un film isolant entourant la surface externe des couches semi-conductrices, le solvant pour diodes électroluminescentes étant un solvant organique présentant un pKa allant de 7 à 15. 발광 소자 용매, 이를 포함하는 발광 소자 잉크 및 표시 장치의 제조 방법이 제공된다. 발광 소자 잉크는 발광 소자 용매 및 상기 발광 소자 용매에 분산되고, 복수의 반도체층들 및 상기 반도체층들의 외면을 둘러싸는 절연막을 포함하는 발광 소자를 포함하고, 상기 발광 소자 용매는 pKa가 7 내지 15의 범위를 갖는 유기 용매이다.
