Claim:
1. An organic electroluminescent element, comprising: a light transmissive electrode; a light reflective electrode; three light-emitting units being provided between the light transmissive electrode and the light reflective electrode; the three light-emitting units being stacked in layers; an interlayer being provided between adjoining light-emitting units, and configured to inject an electrical charge into each light-emitting unit adjacent thereto; two light-emitting units of the three light-emitting units being similar-color light-emitting units that emit light in a similar color, and that have mutually different luminance lives; and a remaining light-emitting unit of the three light-emitting units being a different-color light-emitting unit that emits light in a color that is different from the similar color, and that has a luminance life that is shorter than each luminance life of the two similar-color light-emitting units.
