ABSTRACT:
A high-efficiency, white organic electroluminescent device has such a structure that its emission layer is obtained by laminating sub-emission layers of red, green, and blue, respectively. The green sub-emission layer contacting a hole transport layer has a delayed fluorescent material, and the red sub-emission layer has a phosphorescent light emitting material.
