Abstract
The present invention discloses a top-emitting OLED device, a method of manufacturing the same, and a display panel. The OLED device includes a substrate, an anode layer, an organic functional layer, a cathode layer, and an auxiliary electrode layer sequentially arranged, wherein the auxiliary electrode layer is arranged on the non-light emitting region of the cathode layer, and the material of the auxiliary electrode layer is electrically conductive. The present invention can increase the conductivity of the cathode layer, reduce the voltage difference between the center and the edge of the screen, and improve the display effect without blocking the light emitting region and not affecting the display brightness of the light emitting region.
