Patent ID: 6917394

Claim:
An array substrate for use in a liquid crystal display device, comprising: a substrate; at least a gate line, a gate electrode and a metal island pattern which are formed on the substrate, the gate line arranged in a transverse direction, the gate electrode extending from the gate line, the metal island pattern disposed next to the gate electrode and isolated from the gate electrode and the gate line; a gate insulation layer formed on the substrate while covering the gate line, the gate electrode and the metal island pattern; an active line and an active layer on the gate insulation layer, and an ohmic contact layer on the active line and on the active layer, wherein the active line is arranged in a longitudinal direction perpendicular to the gate line and the active layer extends from the active line over the gate electrode and over the metal island pattern; at least a data line, a source electrode, a drain electrode and a capacitor electrode, wherein the data line is arranged in a longitudinal direction to overlap the active line and defines a pixel region with the gate line, wherein the a source electrode is on the ohmic contact layer and extends from the data line, wherein the drain electrode is disposed on the ohmic contact layer over the metal island pattern and spaced apart from the source electrode, and wherein the capacitor electrode is positioned over the gate line and has an island shape; a passivation layer on the gate insulation layer to cover the data line, the source electrode, the drain electrode and the capacitor electrode, wherein the passivation layer has a drain contact hole to the drain electrode over the metal island pattern and a storage contact hole to the capacitor electrode, and wherein the storage contact hole is disposed over the gate line; and a pixel electrode formed on the passivation layer in the pixel region, the pixel electrode contacting the drain electrode and the drain electrode through the drain contact hole and through the storage contact hole, respectively.
