Claim 10:
11. A method of manufacturing the light emitting device of claim 7, comprising
providing the first electrode,
forming the first auxiliary layer comprising nickel oxide nanoparticles having the average particle diameter of less than or equal to about 10 nanometers on the first electrode,
forming the quantum dot layer on the first auxiliary layer, and
forming the second electrode on the quantum dot layer to manufacture the light emitting device,
wherein the forming the first auxiliary layer comprises
obtaining the nickel oxide nanoparticles from a precursor mixture comprising a nickel oxide precursor,
obtaining a composition for the first auxiliary layer comprising the nickel oxide nanoparticles, and
coating the composition for the first auxiliary layer to form the first auxiliary layer, and

wherein the obtaining the nickel oxide nanoparticles from the precursor mixture further comprises obtaining the organic ligand from the precursor mixture, the precursor mixture further comprises an organic ligand precursor, wherein the organic ligand precursor comprises the substituted or unsubstituted C1 to C10 alkylamine compound, the substituted or unsubstituted C2 to C10 carboxylic acid compound, or the combination thereof.
