1. An organic electroluminescence device, comprising:
a first electrode;
a second electrode facing the first electrode; and
a plurality of organic layers between the first electrode and the second electrode,
wherein at least one organic layer of the plurality of organic layers comprises an amine compound,

wherein each substituent of the substituted aryl group is selected from the group consisting of a deuterium atom, a halogen atom, a cyano group, a nitro group, a silyl group, an oxy group, a sulfinyl group, a sulfonyl group, a carbonyl group, a boron group, a phosphine oxide group, a phosphine sulfide group, an alkyl group, an alkenyl group, an alkoxy group, a hydrocarbon ring group, an aryl group, and a heterocyclic group, the heterocyclic group being selected from the group consisting of a thiophene group, a furan group, a pyrrole group, an imidazole group, a thiazole group, an oxazole group, an oxadiazole group, a pyridine group, a bipyridine group, a pyrimidine group, a triazine group, a triazole group, an acridyl group, a pyridazine group, a pyrazinyl group, a quinoline group, a quinazoline group, a quinoxaline group, a phenoxazine group, a phthalazine group, a pyrido pyrimidine group, a pyrido pyrazine group, a pyrazino pyrazine group, an isoquinoline group, an indole group, a carbazole group, an N-arylcarbazole group, an N-heteroarylcarbazole group, an N-alkylcarbazole group, a benzoxazole group, a benzothiazole group, a benzocarbazole group, a benzothiophene group, a dibenzothiophene group, a benzofuran group, a phenanthroline group, a thiazole group, an isoxazole group, an oxazole group, an oxadiazole group, a thiadiazole group, a phenothiazine group, a dibenzosilole group, and a dibenzofuran group, and
wherein the amine compound is a monoamine compound, in which only one amine group exists in its molecular structure without forming a ring,
when one of the two other groups is an unsubstituted phenyl group, then the two other groups are different from each other, and
when the amine group is directly linked to the one phenyl group contained in the tetraphenylethylene group and one or both of the two other groups are each an unsubstituted aryl group, then the unsubstituted aryl group has 6 to 13 ring-forming carbon atoms.
