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 16):
A method for manufacturing a light-emitting element comprising:\n forming a functional layer containing at least a light-emitting layer between the first and second electrodes, wherein the forming the functional layer includes forming a first light-emitting layer, forming a second light-emitting layer, and forming a third light-emitting layer, the first light-emitting layer has the shortest emission peak wavelength of the light-emitting layers 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 second light-emitting layer contains at least a thermally activated delayed fluorescent material, the excited triplet level of the thermally activated delayed fluorescent material is higher than the excited triplet level of at least one of the host material and the TTF material contained in the first light-emitting layer, the third light-emitting layer has the longest emission peak wavelength of the light-emitting layers and contains at least a fluorescent material, and the forming the first light-emitting layer and the forming the second light-emitting layer are continuously performed such that the second light-emitting layer is layered between the first light-emitting layer and the third light-emitting layer and the first light-emitting layer and the second light-emitting layer are adjacent to each other.
