The invention discloses an array substrate, a manufacture method for an array substrate and a display device and relates to the display technical field. The array substrate comprises a test circuit connected with a work circuit interface and a test interface; the test circuit comprises at least one cut-off point, two ends of each cut-off point on the test circuit are respectively provided with a conductive contact running through the upper surface of the array substrate; while performing the test to the work circuit, the conductive contacts at two ends of all cut-off points are switched on for having breakover for the test circuit. At least one cut-off point is formed on the test circuit during the forming process of the test circuit, and the sub test circuit cut from the cut-off point is not long, so that the antenna effect caused by longer test circuit is reduced, and the problem that the work circuit is damaged by the charge collected by the slender test circuit for the antenna effect of the related technology can be solved; the work circuit is not damaged by the test circuit due to the antenna effect.
