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 1×104Ω·cm or greater and 5×106Ω·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.

Abstract: An electronic device includes a substrate, a first electrode, a second electrode, and a protective film. The substrate includes an element region. The first electrode is provided in the element region on the substrate. The second electrode faces the first electrode and is provided across from the element region to an outside of the element region. The second electrode includes a first electrically conductive film. The protective film covers the first electrically conductive film. The protective film has an end part under which the first electrically conductive film is disposed.
