Abstract

A display device, array substrate and manufacturing method thereof are provided. The array substrate includes an active area and a non-active area, and the active area includes a plurality of scan lines and a plurality of data lines intersecting with the plurality of scan lines, and a plurality of pixel units formed by the intersecting plurality of scan lines and plurality of data lines; the non-active area includes a driving circuit providing scan signals to the scan lines, and the driving circuit is located along an extension direction of the data lines so as to reduce area size of the non-active area along an extension direction of the scan lines to achieve narrowing border size. As such, the ultra-narrow border for display device is achieved.
