Organic electroluminescent element |
| abstract |
The present invention provides an organic electroluminescent device having a light emitting layer including a dopant between a first electrode and a second electrode, wherein the light emitting layer comprises at least two kinds of phosphorescent host materials, and the phosphorescent host material has a thickness of the light emitting layer. Accordingly, there is provided an organic electroluminescent device that exists to have a gradual concentration gradient. The organic electroluminescent device of the present invention improves the efficiency and lifespan characteristics of the device by using a concentration gradient of the host material. |
