Patent ID: 7019797

Claim:
An array substrate for a liquid crystal display device, comprising: a substrate; gate and data lines crossing each other on the substrate; a thin film transistor connected to the gate and data lines, the thin film transistor having a gate electrode, a semiconductor layer, and source and drain electrodes facing and spaced apart from each other; a passivation layer over the gate and data lines and the thin film transistor, the passivation layer having a contact hole exposing a portion of a side edge surface of the drain electrode; a gate insulation layer formed underneath the passivation layer, wherein the contact hole is defined through the passivation layer and the gate insulation layer; a pixel electrode on the passivation layer; and a storage capacitor including a portion of the gate line as a first storage electrode, a portion of the gate insulation layer, and second storage electrode having an island shape, wherein the second storage electrode is disposed directly contacting the gate insulation layer.
