PROBLEM TO BE SOLVED: To provide an organic electro-luminescence element material having a long light emission life and an organic luminescence element, a display device and an illumination device using the material. SOLUTION: A metal complex expressed by general formula (1) is used for the EL material. In the formula, for instance, X<SB>1</SB>, X<SB>2</SB>and L<SB>1</SB>are each aβ-diketone; X is N, Y<SB>1</SB>and Y<SB>2</SB>are each CH<SB>2</SB>, R<SB>1</SB>is Ph, CRaRb is a Ph ring, M<SB>1</SB>is Ir, and n, m1 and m2 are each an integer of≤5.
