The present disclosure provides an array substrate and a display device. The array substrate includes a base substrate; a signal transmission line on the base substrate; at least one electrostatic discharging device and an electrostatic discharging signal line coupled to each other and located at a non-display region of the base substrate. The at least one electrostatic discharging device is configured to discharge static electricity generated in the array substrate. The signal transmission line is coupled with the at least one electrostatic discharging device through at least two branch circuits.
