摘要： Embodiments provide is a quantum dot composition that includes quantum dots, a cross-linking agent including four or more moieties represented by Formula A, and a mixed solvent including a first solvent, a second solvent, and a third solvent. The second solvent has a higher boiling point than the first solvent, the second solvent has a lower surface tension than the first solvent, and the third solvent includes a compound represented by Formula 3. Formula A and Formula 3 are explained in the specification:
