    Abstract: The objective is to provide an organic electroluminescent element with an improved luminous efficiency. The organic electroluminescent element has a structure in which a first light-emitting unit containing a phosphorescent red light-emitting material, a second light-emitting unit containing a phosphorescent yellow light-emitting material, and a third light-emitting unit containing a fluorescent blue light-emitting material are stacked with interlayers in-between. A peak emission wavelength of the phosphorescent yellow light-emitting material is in a range of 530 nm to 570 nm. A peak emission wavelength of the fluorescent blue light-emitting material is in a range of 440 nm to 480 nm. The organic electroluminescent element has a ratio of a yellow emission intensity to a blue emission intensity in a range of 1.0 to 2.0. The organic electroluminescent element further has a ratio of a red emission intensity to the blue emission intensity in a range of 1.5 to 3.0.

    Abstract: The organic electroluminescence element includes: a positive electrode; a negative electrode; a plurality of light emitting layers interposed between the positive electrode and the negative electrode; and an interlayer-provided between the plurality of light emitting layers. The interlayer includes: a first layer-containing a nitrogen-containing heterocyclic compound; an alkali metal layer containing an alkali metal; a second layer containing a nitrogen-containing heterocyclic compound; and a hole injection layer containing an electron-accepting organic material. The first layer, the alkali metal layer, the second layer, and the hole injection layer are arranged in this order from the positive electrode to the negative electrode. The second layer is thicker than the alkali metal layer.

    Abstract: Three light-emitting units are included. Two light-emitting units of the three light-emitting units are similar-color light-emitting units that emit light in a similar color, and have mutually different luminance lives. A remaining light-emitting unit of the three light-emitting units is a different-color light-emitting unit that emits light in a color that is different from the similar color, and has a luminance life that is shorter than each luminance life of the two similar-color light-emitting units.
