摘要：
The present invention provides an organic EL element material which can emit light having a high color purity at a low driving voltage, a high luminescence and a high efficiency and exhibits an excellent stability in repeated use. A normal organic electroluminescence element material is provided which is a heterocyclic compound produced by the condensation of a 5- or 6-membered ring with a 5- to 7-membered ring.
