Claim:
1. An array substrate, comprising: a substrate; a first metal layer disposed on the substrate, wherein the first metal layer is formed with a gate of a thin film transistor and a scan line within a display area, and a first metal line within a non-display area; a first insulation layer disposed on the first metal layer, wherein the first insulation layer isolates the first metal layer from a second metal layer; the second metal layer disposed on the first insulation layer; wherein the second metal layer is formed with a source of the thin film transistor, a drain of the thin film transistor and a data line within the display area, and a second metal line within the non-display area; a second insulation layer disposed on the second metal layer, wherein the second insulation layer isolates the second metal layer from a pixel electrode layer; the pixel electrode layer disposed on the second insulation layer; wherein the pixel electrode layer comprises pixel electrodes within the display area and a conductive line within the non-display area; wherein the first metal line, the second metal line and the conductive line are overlapped with each other to be a link line, a plurality of first through holes and a plurality of corresponding second through holes are disposed on the link line; the first through holes expose the first metal line; the second through holes expose the second metal line; the first metal line in the first through hole is connected to the second metal line in the corresponding second through hole through the conductive line; the first through hole penetrates the second insulation layer, the second metal layer and the first insulation layer within the non-display area; the second through hole penetrates the second insulation layer within the non-display area; each of the first through holes is corresponding to two of the second through holes, wherein the second through holes are disposed at two sides of the first through hole.
