Abstract: An inkjet composition for an inkjet printer, a light-emitting device including the same, and a method of manufacturing the light-emitting device are provided. The ink composition may include light-emitting diodes and a solvent. The solvent may have a first viscosity at a first temperature section that may be greater than a second viscosity at a second temperature section. The solvent may include an ester compound of citric acid, glycol, alkanediol, alkanolamine, alkenic acid, alkenol, a pyrrolidone group-containing compound, glycerol, a compound represented by Formula 1, a compound represented by Formula 2, or any combination thereof: Substituents in Formula 1 and Formula 2 may be understood as described in connection with the detailed description. Each of the light-emitting diodes may have a size in a range of about 0.1 μm to about 10 μm.
