A light emitting device solvent, a light emitting device ink comprising same, and a method for manufacturing a display device are provided. The method for manufacturing a display device comprises the steps of: spraying a device ink, which comprises a first device solvent and a light emitting device dispersed in the first device solvent, at a target substrate having a first electrode and a second electrode; forming a second device solvent, which has an isomeric structure of the molecular structure of the first device solvent, and loading the light emitting device on the first electrode and the second electrode; and removing the second device solvent. Solvant de dispositif électroluminescent, encre de dispositif électroluminescent comprenant celui-ci et procédé de fabrication d'un dispositif d'affichage. Le procédé de fabrication d'un dispositif d'affichage comprend les étapes consistant à : pulvériser une encre de dispositif, qui comprend un premier solvant de dispositif et un dispositif électroluminescent dispersé dans le premier solvant de dispositif, au niveau d'un substrat cible ayant une première électrode et une seconde électrode ; former un second solvant de dispositif, qui présente une structure isomérique de la structure moléculaire du premier solvant de dispositif, et charger le dispositif électroluminescent sur la première électrode et la seconde électrode ; et retirer le second solvant de dispositif. 발광 소자 용매, 이를 포함하는 발광 소자 잉크 및 표시 장치의 제조 방법이 제공된다. 표시 장치의 제조 방법은 제1 전극 및 제2 전극이 형성된 대상 기판 상에 제1 소자 용매 및 상기 제1 소자 용매 내에 분산된 발광 소자를 포함하는 소자 잉크를 분사하는 단계, 상기 제1 소자 용매가 갖는 분자구조의 이성질체 구조를 갖는 제2 소자 용매를 형성하고, 상기 제1 전극 및 상기 제2 전극 상에 상기 발광 소자를 안착시키는 단계 및 상기 제2 소자 용매를 제거하는 단계를 포함한다.
