Abstract
(EN)
The purpose of the present invention is to provide an organic electroluminescence element having optimum light emission characteristics. The above problem is solved by an organic electroluminescence element having a light emission layer that contains a compound of formula (1) or a polymeric compound having a plurality of the structure of formula (1), and a compound of formula (2A) or (2B). (In formula (1), ring A, ring B, and ring C are each an aryl ring, etc., X1 and X2 are >O or >N-R, where R is an aryl, etc.; and in formulae (2A) and 2(B), X is an aryl, etc., and Z is a single bond or a divalent group, etc.)
