Abstract
A quantum dot composition includes a scatterer containing an inorganic material, a quantum dot containing a core and a shell surrounding the core, a ligand binding to the quantum dot, a polymer resin in which the quantum dot and the scatterer are dispersed, and a dispersant containing at least one of an acidic substituent or a basic substituent. At least one of the polymer resin or the dispersant includes a same material as the shell and the ligand binds to the polymer resin or dispersant that includes the same material as a shell.
