1. A display device, comprising an anode layer, a hole injection layer, a hole transport layer, a light-emitting material layer, an electron transport layer, an electron injection layer, and a cathode layer arranged in sequence;
wherein the electron injection layer comprises at least one electron injection layer, and at least one high impedance layer is further arranged between at least one of the electron injection layers and the cathode layer, a resistivity of the electron injection layer and a resistivity of the cathode layer are both smaller than a resistivity of the high impedance layer.
