Patent ID: 7387905

Claim:
A method of fabricating an array substrate of a liquid crystal display device, comprising: forming a gate line and a gate electrode on a substrate; forming a common line and a common electrode on the substrate, the common line is parallel to the gate line and the common electrode extends from the common line and includes a plurality of vertical portions; forming a gate insulating layer on the gate line, the gate electrode, the common line, and the common electrode; forming a semiconductor layer on the gate insulating layer over the gate electrode; forming a data line, a source electrode, and a drain electrode on the semiconductor layer, the data line crosses the gate line to define a pixel area, the source electrode is disposed over the gate electrode and is connected to the data line, and the drain electrode is spacing apart from the source electrode; forming a pixel electrode in the pixel area, the pixel electrode is connected to the drain electrode and includes a plurality of vertical parts alternating with the plurality of vertical portions of the common electrode; and forming a passivation layer on the pixel electrode, wherein a portion of the semiconductor layer partly covers a side of the gate electrode disposed between the data line and the drain electrode, and wherein the portion of the semiconductor layer partly covering the side of the gate electrode has a length within a range of about 2 μm to about 3 μm from a crossing point of the gate electrode and the drain electrode alone the side of the gate electrode.
