Abstract： |
The invention is concerned with the organic electroluminescence device, which consists of the anode layer, the organic function layer and the cathode layer, the organic function layer consists of the luminescence layer, the cavity injection layer, the cavity transmission layer, the electron injection layer, the electron transmission layer and at least one layer of the cavity bar layer, the characteristic is: at least one layer of the organic layer doping at least one material that selects from the halide of the bismuth or the oxide of the bismuth. The doping material can adjust the density of the cavity and electron in order to balance them, and also improve the stability of the organic function layer and the life of the organic electroluminescence device. |
