Abstract

A quantum dot composition includes a quantum dot having a surface to which a ligand is bonded, and a thermal decomposition auxiliary compound. The quantum dot composition may be applied to an emission layer of a light emitting element and a display device, thereby improving luminous efficiency of the light emitting element and the display device.
