Array substrate, manufacturing method thereof and display device

Abstract

The present disclosure relates to the field of display technology, and provides an array substrate, a manufacturing method thereof and a display device. The array substrate includes a display region and a wiring region surrounding thereof. The array substrate further includes a base substrate, a first conductive layer, a first insulating layer, a second conductive layer, a second insulating layer and a patterned shielding layer disposed sequentially thereon. The shielding layer includes a shielding portion in the wiring region. The first and second conductive layers include respectively first and second signal lead wires in the wiring region. There is no overlap between orthographic projections of the first and second signal lead wires on the base substrate. A difference between vertical distances from the first signal lead wire and from the second signal lead wire to the shielding layer is smaller than a thickness of the first insulating layer.
