Abstract: Embodiments provide a light-emitting element that includes: a first electrode, a second electrode disposed on the first electrode, an emission layer disposed between the first electrode and the second electrode and including a quantum dot, a hole transport region disposed between the first electrode and the second electrode, and an electron transport region disposed between the first electrode and the second electrode. The emission layer is disposed between the hole transport region and the electron transport region. At least one of the hole transport region and the electron transport region includes a metal nanoparticle, wherein the metal nanoparticle includes a core including a metal oxide and a ligand bonded the core. The ligand includes an acidic functional group, a basic functional group, or an ultraviolet-reactive functional group.
