Abstract
According to one embodiment, an organic electroluminescent device includes a first electrode, a second electrode, an organic light emitting layer and an optical layer. The first electrode has a first major surface and a second major surface opposite to the first major surface and is light transmissive. The second electrode faces a portion of the first major surface. The organic light emitting layer is provided between the first electrode and the second electrode. The organic light emitting layer and the first electrode are disposed between the optical layer and the second electrode. The optical layer is able to transit between a first state where a traveling direction of light emitted from the organic light emitting layer is changed and a second state having a smaller degree of the change in the traveling direction of the light than the first state.
