Patent ID: 7649581

Claim:
A method of fabricating an array substrate of an LCD, the method comprising: forming a gate line, a gate electrode connected to the gate line, a gate pad disposed at an end of the gate line and a first gate insulating layer formed on each of the gate pad, the gate line and the gate electrode on a substrate, wherein the first gate insulating layer on the gate pad has a contact hole, wherein the gate line, the gate electrode, the gate pad and the first gate insulating layer are formed by using a first photoresist pattern; forming a second gate insulating layer on the gate line and the gate electrode, a data line having a data pad, a thin film transistor having a source electrode, an active layer, and a drain electrode, wherein the second gate insulating layer, the data line and the thin film transistor are formed by using a second photoresist pattern; forming a channel insulating layer on an exposed portion of the active layer by plasma process; forming a transparent electrode pattern that contacts the gate pad through the contact hole and covers the data pad and the data line, wherein the data pad is covered completely by the transparent electrode pattern; and forming a pixel electrode in a pixel region and on some portions of the drain electrode, wherein the drain electrode and the pixel electrode are connected by direct contact.
