Abstract
According to one embodiment, a light emitting element includes a first electrode, a second electrode, a light emitting layer, and a conductive section. The second electrode is provided opposite to the first electrode. The light emitting layer is provided between the first electrode and the second electrode. The second electrode includes a plurality of layers, and the plurality of layers include a first layer. The conductive section pierces the first layer in thickness direction. The conductive section includes a conductive material. Each of the plurality of layers includes at least one of Al, Al alloy, Ag, Ag alloy, alkali metals, and alkaline-earth metals and being different from one another.
