Abstract

Embodiments of the present disclosure provide an OLED device, a method of manufacturing the OLED device, and a display panel. The OLED device comprises: a substrate, a first electrode layer, a color filter layer, a light emitting layer and a second electrode layer. The first electrode layer is one of an anode layer and a cathode layer and comprises: a first sub-electrode layer disposed on the substrate; and a second sub-electrode layer electrically connected with the first sub-electrode layer. The color filter layer is disposed on the first sub-electrode layer and the second sub-electrode layer is disposed on the color filter layer. The second electrode layer is the other of the anode layer and the cathode layer and the light emitting layer is disposed between the second electrode layer and the second sub-electrode layer of the first electrode layer.
