摘要： PROBLEM TO BE SOLVED: To provide a highly efficient white organic EL element which eliminates expansion of the barrier between HOMO of a hall transport layer and HOMO of an sub light-emitting layer since the green sub light-emitting layer having a highly efficient delayed fluorescent material is made neighboring the hole transport layer, and enables light emission at high efficiency since a red sub light-emitting layer has a phosphorescent material. SOLUTION: In the white organic EL element, a light-emitting layer is formed by laminating respective red, green and blue sub light-emitting layers, a green light-emitting layer in contact with the hole transport layer has a delayed fluorescent material, and a red light-emitting layer has a phosphorescent material. The HOMO of the delayed fluorescent material having the red sub light-emitting layer is deeper than that of a material having the hole transport layer, and shallower than that of the phosphorescent material having the red sub light-emitting layer.
