Abstract

An organic light-emitting diode device, a manufacturing method thereof, and a display device are provided. The organic light-emitting diode device includes a light-emitting layer, a functional layer, and a cathode layer, wherein a material of the functional layer includes a metal sol containing metal nanoparticles, and the metal sol forms an uneven nanostructure on a surface of the functional layer, which has a scattering effect on light of the light-emitting layer, thereby reducing a binding force between the light and surface electrons of the cathode layer, so surface plasmon polariton waves can be prevented and light extraction efficiency can be improved.
