PROBLEM TO BE SOLVED: To provide an organic electroluminescence device, in which an electronic injection layer which has a superior transport property and a protective function to a luminescence layer are prepared between the luminescence layer and a negative electrode layer. SOLUTION: The organic electroluminescence device contains a positive electrode layer, the luminescence layer, the electronic injection layer, and the negative electrode layer, where the electronic injection layer consists of acetyl- acetonate complex whose central metal is a transition metal, or its derivative thereof.
