| 摘要 |
An organic electroluminescence device includes an anode, a cathode and layers between the anode and the cathode, the layers at least including a hole transporting layer, a first emitting layer, a second emitting layer and an electron transporting layer, in which the first emitting layer includes a first host material and a first luminescent material and the second emitting layer is continuously formed on the first emitting layer near the cathode and includes a second host material and a second luminescent material. The second host material is a monoazine derivative, a diazine derivative, or a triazine derivative. The first and second luminescent materials are different metal complexes.
