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: A display panel including a power supplying auxiliary electrode above the substrate in at least one gap among gaps between pixel electrodes in row and column directions, not in contact with the pixel electrodes, extending in the row and/or column direction. An intermediate layer is on or above light-emitting layers and the auxiliary electrode, and includes a fluoride of an alkali metal or an alkaline earth metal. A functional layer is on or above the intermediate layer, and includes an organic material that facilitates electron transport and/or facilitates electron injection and a rare earth metal dopant. A counter electrode is on or above the functional layer. Further, 1≤x≤3, 20≤y≤40, and y≥10x+10, where x is film thickness of the intermediate layer in nanometers, and y is percentage by weight of the rare earth metal dopant in the functional layer.
