| 发明名称 | Organic EL element | ||
| 摘要 | A technology having resistance to moisture and oxygen, and in which the occurrence and expansion of non-light-generating portions, such as dark spots, are suppressed is provided. An organic EL element in which an organic functional layer including at least one or more light-emitting layers is arranged between a first electrode and a second electrode, wherein the organic functional layer includes a bipolar charge generation layer which generates electrons and holes, and one of the first electrode and the second electrode is a hole-receiving electrode. | ||
