Light emitting element ink and method of manufacturing display device

A light emitting element ink, comprising:

• a light emitting element solvent;
• a light emitting element dispersed in the light emitting element solvent, the light emitting element including:
• a plurality of semiconductor layers;
• and
• an insulating film surrounding outer surfaces of the plurality of semiconductor layers;
• and
• a thickener dispersed in the light emitting element solvent, wherein
• the thickener includes a compound represented by Chemical Structural Formula 1 below as a polyol-based compound capable of forming a hydrogen bond with the light emitting element solvent or another thickener, and
• the thickener has a boiling point in a range of about 200° C. to about 450° C.,
• wherein, in Chemical Structural Formula 1,
• R1 is a linear or branched alkyl group or a linear or branched alkyl ether group having 1 to 3000 carbon atoms,
• the linear or branched alkyl group and the linear or branched alkyl ether group are substituted with a hydroxyl group (—OH) or is unsubstituted, and
• I is an integer of 1 to 10.
