Title:
ORGANIC ELECTROLUMINESCENT ELEMENT
Document Type and Number:
WIPO Patent Application WO/2022/270113
Kind Code:
A1
Abstract:
Provided is an organic electroluminescent element by which high light-emission efficiency can be obtained even in a case in which the LUMO level of a fluorescent material is lower than the LUMO level of a delayed fluorescent material. The organic electroluminescent element contains, in a light-emitting layer, a first organic compound, a second organic compound that is a delayed fluorescent material, and a third organic compound that emits fluorescent light. The LUMO energy of the second organic compound is higher than that of the third organic compound. The largest component of emitted light from the element is fluorescent light from the third organic compound, and the orientation value of the third organic compound in the light-emitting layer is -0.3 or less.
