Abstract:
A light emitting element includes a first electrode, an organic layer formed on the first electrode and including a luminescent layer composed of an organic luminescent material and a second electrode formed on the organic layer, and further includes a light reflecting layer provided below the first electrode. Light emitted in the luminescent layer is resonated between the light reflecting layer and an interface of the second electrode and the organic layer, and a portion of the light is output from the second electrode.
