ORGANIC ELECTROLUMINESCENT ELEMENT

摘要

Disclosed is an organic electroluminescent element that has on a substrate a pair of electrodes and at least one organic layer formed between the electrodes. The organic layer has at least two light-emitting layers and an intermediate layer formed between the light-emitting layers, of which there are at least two. Each of the light-emitting layers, of which there are at least two, contains a phosphorescent material. The phosphorescent material is at least one kind selected from a group comprising blue phosphorescent material having an emission peak of 420 nm to less than 500 nm, green phosphorescent material having an emission peak of 500 nm to less than 570 nm, and red phosphorescent material having an emission peak of 570 nm to less than 650 nm. The phosphorescent materials contained in each of the light-emitting layers have mutually different emission peaks, and the intermediate layer contains a binder material.
