Abstract
A quantum dot composition includes a quantum dot, a ligand to bind to a surface of the quantum dot, an additive having an amine group, and a precursor comprising an organometallic compound, the composition forming a modified quantum dot having a reformed surface characteristic. A light emitting element including the modified quantum dot may have improved lifespan, luminous efficiency, and material stability.
