Abstract:
An organic EL element ( 10 ) includes a first light-emitting layer ( 33 a ) having the shortest emission peak wavelength of a light-emitting layer ( 33 ) and containing a host material and a TTF material or at least the TTF material, a second light-emitting layer ( 33 b ) containing at least a TADF material, a third light-emitting layer ( 33 c ) having the longest emission peak wavelength of the light-emitting layer ( 33 ) and containing at least fluorescent material. The excited triplet level of the TTF material is lower than the excited triplet level of the TADF material.

Claim (Index 17):
A light emission method comprising:\n transferring the energy of excitons generated in a second light-emitting layer containing at least a thermally activated delayed fluorescent material to a first light-emitting layer by Dexter energy transfer; and transferring the energy of excitons generated in the second light-emitting layer to a third light-emitting layer by F\u00f6rster energy transfer to make the first, second, and third light-emitting layers to emit light, wherein the first light-emitting layer is layered on the second light-emitting layer, has an emission peak wavelength shorter than an emission peak wavelength of the second light-emitting layer, and contains a host material and a TTF material or at least the TTF material, the TTF material being a delayed fluorescent material configured to cause a TTF phenomenon in cooperation with the host material or by the TTF material alone, the excited triplet level of at least one of the host material and the TTF material is lower than the excited triplet level of the thermally activated delayed fluorescent material, and the third light-emitting layer is layered on the second light-emitting layer on a side opposite to the first light-emitting layer, has an emission peak wavelength longer than an emission peak wavelength of the second light-emitting layer, and contains at least the fluorescent material.
