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 or 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 or 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.

Abstract: The present disclosure relates to a display substrate. The display substrate may include a base substrate; and a plurality of pixels in a display area on the base substrate. At least one of the plurality of pixels includes a first sub-pixel and a third sub-pixel. The first sub-pixel may include an OLED component that emits light of a first color, the third sub-pixel may include a LED component that emits light of a third color, and the first color and the third color are different colors. All sub-pixels including OLED components may be disposed on a same side of the base substrate, and all sub-pixels including LED components may be disposed on another side of the base substrate opposite the side on which the OLED components are disposed.
