Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
1 . 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. 2 . The organic electroluminescent element according to claim 1 , wherein the different-color light-emitting unit comprises a light-emitting layer containing a blue light-emitting material. 3 . The organic electroluminescent element according to claim 1 , wherein the different-color light-emitting unit comprises a light-emitting layer containing a fluorescent material as a light-emitting material. 4 . The organic electroluminescent element according to claim 1 , wherein the two similar-color light-emitting units comprise respective light-emitting layers that differ in layered structure or composition. 5 . The organic electroluminescent element according to claim 1 , wherein the two similar-color light-emitting units comprise respective light-emitting layers containing a phosphorescent material as a light-emitting material. 6 . The organic electroluminescent element according to claim 1 , wherein the two similar-color light-emitting units comprise respective light-emitting layers containing both a red light-emitting material and a green light-emitting material. 7 . The organic electroluminescent element according to claim 1 , wherein the two similar-color light-emitting units comprise respective light-emitting layers which contain light-emitting materials and each of which contains at least one identical light-emitting material. 8 . The organic electroluminescent element according to claim 1 , wherein the two similar-color light-emitting units comprise respective light-emitting layers which contain light-emitting materials and each of which contains at least one different light-emitting material. 9 . The organic electroluminescent element according to claim 2 , wherein the different-color light-emitting unit comprises a light-emitting layer containing a fluorescent material as a light-emitting material. 10 . The organic electroluminescent element according to claim 2 , wherein the two similar-color light-emitting units comprise respective light-emitting layers that differ in layered structure or composition. 11 . The organic electroluminescent element according to claim 2 , wherein the two similar-color light-emitting units comprise respective light-emitting layers containing a phosphorescent material as a light-emitting material. 12 . The organic electroluminescent element according to claim 2 , wherein the two similar-color light-emitting units comprise respective light-emitting layers containing both a red light-emitting material and a green light-emitting material. 13 . The organic electroluminescent element according to claim 2 , wherein the two similar-color light-emitting units comprise respective light-emitting layers which contain light-emitting materials and each of which contains at least one identical light-emitting material. 14 . The organic electroluminescent element according to claim 2 , wherein the two similar-color light-emitting units comprise respective light-emitting layers which contain light-emitting materials and each of which contains at least one different light-emitting material.
