Abstract
An organic electroluminescent element according to one embodiment of the disclosure includes a first reflective layer, a second reflective layer, an organic light-emitting layer, a silver electrode layer, and an ytterbium electron injection layer. The organic light-emitting layer is provided between the first reflective layer and the second reflective layer, and emits monochromatic light. The silver electrode layer is provided between the organic light-emitting layer and the second reflective layer. The ytterbium electron injection layer is in contact with the silver electrode layer on side of the organic light-emitting layer.
