The utility model relates to the technical field of semiconductor packaging, in particular to a light-emitting device, a display panel and a display device. A light emitting unit; a flat layer; a conductive layer; and an encapsulation layer; wherein the first electrodes of the light-emitting diode chips are electrically connected to the same welding area, the second electrodes of the light-emitting diode chips are electrically connected to different welding areas respectively, the projection areas of the welding areas on the substrate at least partially coincide with the projection areas of the light-emitting diode chips on the substrate, and the first electrodes of the light-emitting diode chips are electrically connected to the same welding area. And gaps are formed between the welding areas. The projection areas of the welding areas on the substrate and the projection areas of the light emitting diode chips on the substrate are partially or completely overlapped, namely, the welding areas are arranged abov
