Abstract: An organic light-emitting diode display substrate, a display panel and a display device. The display substrate includes a source/drain layer (101), a planarization layer (102) and an anode layer (103) which are laminated in sequence; the source/drain layer (101) comprises at least one pair of first signal lines (110); the anode layer (103) comprises a common power line (130), and the common power line (130) is provided with an air discharge hole (131); and the overlapping areas of a projection pattern of the air discharge hole (131) and two first signal lines (110) in any pair of first signal lines (110) are equal, the overlapping areas are greater than 0, and the projection pattern of the air discharge hole (131) is a pattern of an orthographic projection, on the source/drain layer (101), of the air discharge hole (131) on the common power line (130). The overlapping areas of the common power line (130) and the two first signal lines (110) in the pair of first signal lines (110) are equal, so that the parasitic capacitances between the common power line (130) and the two first signal lines (110) in the pair of first signal lines (110) are the same in magnitude, and so that signals transmitted by the pair of first signal lines (110) match each other, ensuring the uniformity of a display screen.
