Claim 14:
15. A method of manufacturing a light-emitting device, the method comprising:
providing a quantum dot composition on a first electrode,
wherein the quantum dot composition comprises:
a first solvent,
a second solvent different from the first solvent,
first quantum dots comprising a hole-transporting ligand, and
second quantum dots comprising an electron-transporting ligand,
wherein the first solvent and the second solvent are miscible solvents having different boiling points from each other, a degree of dispersion of the first quantum dots is greater in the first solvent than in the second solvent, and a degree of dispersion of the second quantum dots is greater in the second solvent than in the first solvent,

forming a first emission layer by removing a solvent having a lower boiling point among the first solvent and the second solvent;
forming a second emission layer by removing a solvent having a higher boiling point among the first solvent and the second solvent; and
forming a second electrode on the second emission layer.
