Abstract
A quantum dot composition may include: a first solvent; a second solvent different from the first solvent; first quantum dots including a hole-transporting ligand; and second quantum dots including 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.
