Abstract
An organic electroluminescent element has a first electrode, a second electrode and an organic electroluminescent layer. The first electrode has a first luminescent region and a first terminal extending from the first luminescent region. The second electrode has a second luminescent region and a second terminal extending from the second luminescent region. The first electrode is made of a material having a higher volume resistivity than the second electrode. The organic electroluminescent layer is interposed between the first electrode and the second electrode. The first luminescent region and the second luminescent region respectively contact the organic electroluminescent layer. A length of a boundary between the first luminescent region and the first terminal is greater than a length of a boundary between the second luminescent region and the second terminal.
