摘要： Provided are a light-emitting element solvent, a photodegradable thickener, a light-emitting element ink comprising same, and a method for manufacturing a display device. The method for manufacturing a display device comprises the steps of: spraying, on a target substrate having a first electrode and a second electrode formed thereon, an element ink comprising a first element solvent and light-emitting elements dispersed in the first element solvent; forming a second element solvent in which at least some bonds of the first element solvent are decomposed by irradiating light to the first element solvent and mounting the light-emitting elements on the first electrode and the second electrode; and removing the second element solvent.
