摘要:
Disclosed is an organic electroluminescence device having a longer drive life. The organic electroluminescence device includes a light emitting layer which contains a luminescent dye and a host material having a nitrogen-containing aromatic heterocyclic ring. The luminescence resulting from the hole transport layer adjacent to the light emitting layer is less than one-hundredth of the luminescence resulting from the luminescent dye.
