Abstract
An array substrate for an LCD device includes a gate line crossing a data line to define a pixel region. A thin film transistor (TFT) includes a gate electrode connected to the gate line, insulating and active layers on the gate electrode, a source electrode connected to the data line, and a drain electrode spaced apart from the source electrode. An auxiliary common electrode includes a horizontal portion disposed in the pixel region. A metal layer overlaps the insulating layer and contacts the horizontal portion of the auxiliary common electrode through a contact hole defined through the insulating layer. A passivation layer is disposed on the TFT and the metal layer. A pixel electrode has a horizontal portion overlapping the metal layer with the passivation layer therebetween to form a storage capacitor, the pixel electrode connected to the drain electrode through a second contact hole defined through the passivation layer.
