Abstract:
1. An array substrate for a liquid crystal display device, comprising: a substrate; a gate line over the substrate; a data line crossing the gate line to define a pixel region, the data line including a transparent conductive layer and a conductive metallic layer; a data pad at one end of the data line and including a transparent conductive layer; a thin film transistor connected to the gate line and the data line and including a gate electrode, an active layer, an ohmic contact layer, a source electrode and a drain electrode, wherein each of the source electrode and the drain electrode includes a transparent conductive layer and a conductive metallic layer; and a pixel electrode in the pixel region and connected to the thin film transistor, wherein the pixel electrode and the transparent conductive layer of the drain electrode are formed of the same layer and the same material, and wherein the active layer has an island shape and is disposed over and within the gate electrode.
