1. A method of manufacturing a display device, comprising:
preparing a light emitting element ink comprising a light emitting element solvent, a plurality of light emitting elements, and a thickener, and preparing a target substrate comprising a first electrode and a second electrode on the target substrate;
ejecting the light emitting element ink onto the target substrate;
forming an electric field on the target substrate to place the light emitting elements on the first electrode and the second electrode; and
heat-treating the light emitting element ink under a low-pressure environment to remove the light element solvent and the thickener,
wherein a compound of the thickener of the light emitting element ink comprises a functional group capable of forming a hydrogen bond together with a compound of the light emitting element solvent or another compound of the thickener, and comprises a compound represented by Chemical Formula 1 below:
![]() wherein, in Chemical Formula 1, each R1 is independently a substituted or unsubstituted alkyl group having 6 to 8 carbon atoms, an alkene group, an alkenyl group, or an alkynyl group, and each R2 is independently an alkyl group having 3 to 8 carbon atoms.
