A top-emitting flexible organic light emission diode device and preparation method thereof are provided. The device involves overlapping a substrate, an anode layer, a hole injection layer, a hole transport layer, an emission layer, an electron transport layer, an electron injection layer and a cathode layer sequentially. The material of the cathode is scythe-silver alloy or ytterbium-silver alloy. The method for preparing the device comprises the following steps: cleaning and drying the substrate; depositing the anode layer on the surface of the substrate; overlapped depositing the hole injection layer, the hole transport layer, the emission layer, the electron transport layer and the electron injection layer sequentially on the surface of the anode layer; depositing the cathode layer on the surface of the electron injection layer to obtain the device. |
