Abstract:
A light-emitting element containing a fluorescent material and having high emission efficiency is provided. The light-emitting element contains the fluorescent material and a host material. The host material contains a first organic compound and a second organic compound. The first organic compound and the second organic compound can form an exciplex. The minimum value of a distance between centroids of the fluorescent material and at least one of the first organic compound and the second organic compound is 0.7 nm or more and 5 nm or less.

Claim (Index 9):
A light-emitting element comprising:\n a pair of electrodes; and a light-emitting layer between the pair of electrodes, wherein the light-emitting layer comprises:\n a fluorescent material as a guest material; and \n a first organic compound and a second organic compound capable of forming an exciplex as a host material, \n wherein the fluorescent material has a fluorescence quantum yield of 70% or higher, and wherein the fluorescent material comprises two substituents, wherein the two substituents comprise any one of branched alkyl groups each having 3 to 10 carbon atoms, cyclic hydrocarbon groups each having 3 to 10 carbon atoms, bridged cyclic hydrocarbon groups each having 3 to 10 carbon atoms, and wherein light emitted from the exciplex has a region overlapping with an absorption band of the fluorescent material on the lowest energy side.
