1. An OLED display device, comprising:

  • the light-emitting diode comprises a substrate (10), an anode (20) formed on the substrate (10), a hole injection layer (30) formed on the anode (20), a hole transport layer (40) formed on the hole injection layer (30), a light-emitting layer (50) formed on the hole transport layer (40), a hole blocking layer (60) formed on the light-emitting layer (50), an electron transport layer (70) formed on the hole blocking layer (60), an electron injection layer (80) formed on the electron transport layer (70), a cathode (90) formed on the electron injection layer (80), a cover plate (100) which is arranged opposite to the substrate (10) and covers the substrate (10), and an encapsulating adhesive (110) arranged between the edge of the substrate (10) and the cover plate (100);

    the material of the electron transport layer (70) is a mixture of an organic electron transport material and an organic metal halide perovskite material;

    in the mixture of the organic electron transport material and the organic metal halide perovskite material, the mixing mass ratio of the organic electron transport material to the organic metal halide perovskite material is 1;

    0.5 to 1;

    50;

    the electron transport layer (70) is prepared by a wet film forming process.
