Abstract: A light-emitting element has a layer including an organic material between a first electrode and a second electrode, and further has a layer including a metal oxide between the second electrode and the layer including the organic material, where these electrodes and layers are laminated so that the second electrode is formed later than the first electrode. The light-emitting element is suppressed damage caused to a layer including an organic material during deposition by sputtering and a phenomenon such as short circuit between electrodes.
