Abstract: An array substrate includes a base substrate and at least three layers of signal lines insulated from each other and arranged in a non-display region. The signal lines include first signal lines in a first layer and second signal lines in a second layer extending in an identical direction, and third signal lines in a third layer crossing the first and the second signal lines. A distance between each third signal line and the base substrate is larger than a distance between each first/second signal line and the base substrate. An orthogonal projection of each first signal line on the base substrate overlaps that of the corresponding third signal line to form a first overlapping region, an orthogonal projection of each second signal line overlaps that of the corresponding third signal line to form a second overlapping region which partially overlaps, or does not overlap, the first overlapping region.
