摘要：
A display device includes an anode electrode a cathode electrode a light-emitting layer, and an electron transport layer. The light-emitting layer is provided between the anode electrode and the cathode electrode. The electron transport layer is provided between the cathode electrode and the light-emitting layer. The electron transport layer includes a nanoparticle of a metal oxide, and an organic modifier configured to cover a surface of the nanoparticle and having electron donating characteristics.
