Claim 14:
15. A manufacturing method of an organic light-emitting diode device, comprising following steps:
providing a substrate and forming an anode layer, a hole transport layer, a light-emitting layer, and an electron transport layer on the substrate in sequence;
coating a layer of metal sol on one side of the electron transport layer away from the light-emitting layer, wherein the metal sol comprises metal nanoparticles, and the metal sol is cured to form a functional layer and an uneven nanostructure on one side surface of the functional layer away from the electron transport layer; and
manufacturing a cathode layer on one side of the functional layer away from the electron transport layer.
