An organic electro luminescence device is provided to improve the light-emitting property and physical property of device by improving the organic layer formed between electrodes. The organic electro luminescence device comprises a pair of electrode, and the light-emitting layer and the organic layer. The organic layer is formed between electrodes. The organic layer shows as the chemical formula (I). Here, R^1 or R^7 is the hydrogen atom or the substitution radical. However, At least one among R^1 or R^7 is the heavy hydrogen atom or the substitution radical containing the heavy hydrogen atom. |
