Abstract
Three light-emitting units are included. Two light-emitting units of the three light-emitting units are similar-color light-emitting units that emit light in a similar color, and have mutually different luminance lives. A remaining light-emitting unit of the three light-emitting units is a different-color light-emitting unit that emits light in a color that is different from the similar color, and has a luminance life that is shorter than each luminance life of the two similar-color light-emitting units.
Claims14
An organic electroluminescent element, comprising:
- three light-emitting units,
- the three light-emitting units being stacked in layers,
- an interlayer being provided between adjoining light-emitting units,
- two light-emitting units of the three light-emitting units being similar-color light-emitting units that emit light in a similar color, and 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 has a luminance life that is shorter than each luminance life of the two similar-color light-emitting units.
