Light-emitting device and method of manufacturing the same

A method of manufacturing a light-emitting device, the method comprising:

• preparing a first electrode;
• forming a charge transport layer by providing, on the first electrode, an inorganic nanoparticle composition comprising an inorganic nanoparticle and a solvent, the inorganic nanoparticle comprising a second ligand bonded to a surface thereof;
• forming a preliminary emission layer by providing, on the charge transport layer, a quantum dot composition comprising a quantum dot, a cross-linking agent, and a solvent, the quantum dot comprising a first ligand bonded to a surface thereof;
• forming an emission layer by performing at least one selected from among a heat treatment and a UV irradiation on the preliminary emission layer;
• and
• forming a second electrode on the emission layer.
