Abstract

Disclosed are a light-emitting device and a method of manufacturing the same. The light-emitting device includes: a first electrode; a second electrode facing the first electrode; an emission layer between the first electrode and the second electrode and including a quantum dot including a first ligand bonded to a surface thereof; and a charge transport layer including an inorganic nanoparticle including a second ligand bonded to a surface thereof, wherein an interface between the emission layer and the charge transport layer includes a cross-link in which the first ligand on the surface of the quantum dot and the second ligand on the surface of the inorganic nanoparticle are linked by a cross-linking agent.
