Abstract:
An organic EL element includes: a first electrode that is a metal layer; a transparent conductive layer containing indium zinc oxide; and a light-emitting layer, wherein the first electrode, the transparent conductive layer, and the light-emitting layer are stacked, and a ratio of zinc to indium in a vicinity of an interface of the transparent conductive layer is lower than or equal to 0.25, the interface being closer to the light-emitting layer.
