摘要：
A quantum dot composition includes a quantum dot, and a ligand bonded to a surface of the quantum dot, wherein the ligand includes a head portion bonded to the surface of the quantum dot, a connecting portion connected to the head portion and including a metal, and a tail portion coordinated to the metal of the connecting portion. The quantum dot composition according to the present embodiments is used to form an emission layer of a light emitting element, and may thus increase service life and luminous efficiency of the light emitting element including the emission layer formed using the quantum dot composition.
