The application provides an array substrate, a display panel, and a display device. The display panel comprises the support plate and the array substrate. The backlight surface of the flexible driving circuit substrate of the array substrate is bonded to the support plate in the display area. The area where the flexible driving circuit substrate is provided with the gate driving circuit and the data driving circuit is bent and attached to the other surface of the support plate. The light emitting surface of the display panel only has a display area capable of displaying pictures, which alleviates the problem that the existing display panel cannot fully display.
