Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a material for an organic electroluminescent element that has high thermal stability and long light emission life, the organic electroluminescent element, a display device, and a lighting system.SOLUTION: This material for the organic EL element is represented by general formula (1). In general formula (1), each of Arand Arshows an aromatic hydrocarbon group or aromatic heterocyclic group. Each of Y-Yshows a nitrogen atom or CR-CR. Each of R, R, R, R, Rand Rshows a hydrogen atom, alkyl group, aromatic hydrocarbon group, aromatic heterocyclic group, amino group, silyl group, germyl group, or stannyl group. Each of Rand Rshows a hydrogen atom. X shows single bond -CRR-, -CR=CR-, -SiRR-, -O-, -NR-, -S-, -PR-, -P(=O)R-, -GeRR-, or -SnRR-. Each of R-Rshows a hydrogen atom, aromatic hydrocarbon group or aromatic heterocyclic group.
