See full text

According to one embodiment, an organic electroluminescent element includes a substrate, a first electrode, a second electrode, an organic layer and a first conductive unit. The substrate is light-transmissive. The second electrode is provided between the substrate and the first electrode. The second electrode is light-transmissive. The second electrode includes a first region and a second region. A direction connecting the first region and the second region intersects a first direction connecting the substrate and the first electrode. The organic layer is provided between the second electrode and the first electrode. The first conductive unit is provided between the first region and a portion of the substrate. The first conductive unit is electrically connected with the second electrode. The first conductive unit includes a third region and a fourth region. A portion of the fourth region is disposed between the substrate and at least a portion of the third region.
