Abstract:
1. An array substrate of a liquid crystal display device comprising: a gate line formed on an array substrate and a gate electrode diverged from the gate line; a storage capacitor line composed of a transparent conductive material and arranged parallel to the gate line, wherein the storage capacitor line has a first area and a second area, the first area is formed by a first width and a second area is formed by a second width, the first width is wider than the second width; a gate insulating film covering the gate line, the gate electrode, and the storage capacitor line; a semiconductor layer formed to overlap the gate electrode on the gate insulating film; source and drain electrodes arranged with a constant interval on the semiconductor layer; a data line connected to the source electrode and arranged perpendicularly to the gate line, wherein the data line is overlapped the second area of the storage capacitor; an insulating layer formed on the data line, the source/drain electrodes, and the gate insulating film; a first contact hole formed by removing the insulating layer so as to expose a part of the drain electrode; a pixel electrode connected to the drain electrode through the first contact hole above the insulating layer; wherein the pixel electrode is overlapped the first area of the storage capacitor, wherein a length of the first area of the storage capacitor line in an extended direction is wider than that of the pixel electrode; a storage capacitor electrode formed in the same layer as the source/drain electrodes, arranged in the pixel electrode to overlap the first area of the storage capacitor line, and composed of a transparent conductive material; and a second contact hole which exposes a part of the storage capacitor electrode on the insulating layer so as to be electrically connected to the pixel electrode.
