Abstract
According to one embodiment, an organic electroluminescent device includes first and second electrodes, an interconnection layer, an organic light emitting layer and a light scattering layer. The first electrode has includes first, second and third portions. The interconnection layer is electrically connected to the first electrode. The third portion overlays the interconnection layer when projected to the plane. The first and second portions do not overlay the interconnection layer. The second electrode overlays the second portion and does not overlay the first and the third portions. The organic light emitting layer is provided between the second portion and the second electrode. The second portion is disposed between the fourth portion of the light scattering layer and the second electrode. The fifth portion of the light scattering layer overlays the interconnection layer. The light scattering layer does not overlay the first portion when projected to the plane.
