Abstract: An organic electroluminescent device includes, in order, a first electrode, a light-emitting layer, a resistive layer, and a second electrode. The resistive layer has a specific resistance within a range of 1×104 Ω·cm or greater and 5×106 Ω·m or less and includes a mixed material including two or more of zinc oxide, gallium oxide, and silicon dioxide and having a composition ratio within a predetermined range.
