The invention discloses an array substrate, a display panel and a display device, relating to the field of display technology, including a display area and a non-display area surrounding the display area, the non-display area includes a single-layer area, and the single-layer area includes A plurality of pads on the cloth and a plurality of shorting bars corresponding to the pads along the second direction, the maximum length of the pads along the second direction is d1, the maximum length of the shorting bars along the second direction is d2, and the pads are close to the display The furthest distance along the second direction from one end of the zone to the straight line where the second edge lies is D1, wherein at least part of d1+d2<D1. In this application, by blocking the path of electrostatic charge transmission, the electrostatic charge generated by the friction between the array substrate and the device base is prevented from being transmitted to the display area, and the problem of poor display caused by the electric field generated by the accumulation of electrostatic charge is avoided.
