Patent ID: 8178883

Claim:
An array substrate for a liquid crystal display device, comprising: a substrate; a gate line, a gate pad, a gate electrode, a data pad and a link portion extending from the data pad on the substrate; a gate insulating layer covering the gate line, the gate pad, the gate electrode, the data pad and the link portion; an active layer on the gate insulating layer over the gate electrode; an ohmic contact layer on the active layer; a source electrode, a drain electrode and a data line on the ohmic contact layer, the data line crossing the gate line to define a pixel region, and one end of the data line overlapping the link portion; and a pixel electrode in the pixel region, a gate pad terminal contacting the gate pad, and a data pad terminal contacting the data pad and the data line, wherein the gate insulating layer includes a data pad contact hole exposing the data pad, wherein the data line and the gate insulating layer include a link contact hole exposing the link portion, wherein the data pad terminal contacts the data pad through the data pad contact hole and contacts the link portion through the link contact hole, and wherein the data pad terminal directly contacts a whole top surface of the data line without an intervening insulating layer.
