Abstract: An organic electroluminescent (EL) element includes: a first electrode; an interlayer formed above the first electrode; an organic light-emitting layer formed using the interlayer as a foundation; and a second electrode formed above the organic light-emitting layer. The organic light-emitting layer contains at least a host material and a dopant material. The interlayer is formed using a material which has an energy gap larger than an energy gap of the dopant material and a highest occupied molecular orbital (HOMO) level deeper than a HOMO level of the dopant material.

Abstract: An organic electroluminescent unit is provided with a plurality of organic electroluminescent elements. At least one of the organic electroluminescent elements includes, in order, a first electrode, a hole transport layer, a light-emitting layer, an electron transport layer, and a second electrode. The hole transport layer, the light-emitting layer, and the electron transport layer satisfy the following expressions: ΔEg(T1)≥0 eV ΔEg(T1)=ETa+ETb−2×ETEML where ETa represents a T1 level of the hole transport layer, ETb represents a T1 level of the electron transport layer, and ETEML represents a T1 level of the light-emitting layer.
