Zusammenfassung:An organic light-emitting device includes an anode electrode and a cathode electrode that are arranged facing each other; a light-emitting layer arranged between the anode electrode and the cathode electrode; and a hole transport layer arranged between the anode electrode and the light-emitting layer, and including one or more layers. A layer, of the one or more layers of the hole transport layer, contacting the light-emitting layer has a HOMO energy level 12bH that is higher than a HOMO energy level 13H of the light-emitting layer. A difference ΔE1 between the HOMO energy level 12bH of the layer contacting the light-emitting layer of the hole transport layer and the HOMO energy level 13H of the light-emitting layer is 0.32 eV or less.
