An array substrate of the present invention includes a storage capacitor that has a storage-on-gate structure. One embodiment of the present invention discloses the array substrate having a metal island pattern on the substrate beneath a drain electrode. The metal island pattern is disposed beneath a drain contact hole through which a pixel electrode contacts the drain electrode. Since the metal island pattern has the same thickness as the gate line, the passivation layer can have the same height both in a drain region and in a storage region. Over-etching is minimized with the passivation layer in the drain and storage region having the same uniform thickness.

Array substrate and method thereof for liquid crystal display device

An array substrate of the present invention includes a storage capacitor that has a storage-on-gate structure. The storage capacitor includes a gate line as a first electrode and a capacitor electrode as a second electrode. The capacitor electrode particularly has an extension that protruding from the capacitor electrode into a pixel region. Thus, when connecting a pixel electrode to the storage capacitor, the pixel electrode contacts the extension of the capacitor electrode. Since a storage contact hole through which the pixel electrode contacts the extension, a short between the pixel electrode and the gate line in the storage capacitor is prevented.
