An array substrate includes a substrate as well as a first insulating layer, a first conductive layer, a second insulating layer, a second conductive layer and a conductive structure sequentially formed thereon. The first insulating layer has a first opening communicated with a through hole of the substrate. The first conductive layer includes a first ring pattern extending from top of the first insulating layer into the first opening. The second insulating layer has a second opening communicated with the first opening. The second conductive layer includes a second ring pattern extending from top of the second insulating layer into the second opening. The first ring pattern laterally protrudes toward an axis of the through hole from the second ring pattern. The conductive structure extends from above the second insulating layer to a bottom surface of the substrate through the first and second openings and the through hole.
