Patent ID: 7548284

Claim:
A fabricating method of an array substrate of a liquid crystal display device, comprising: forming a gate line disposed along a first direction and a common line parallel to the gate line on a substrate, the gate and common lines spaced apart from each other; forming a gate insulating layer on the gate and common lines; forming a semiconductor layer on the gate insulating layer; forming a source electrode and a pixel electrode of transparent conductive material, the pixel electrode including a drain electrode portion, the drain electrode portion overlapping the semiconductor layer, the source electrode spaced apart from the drain electrode portion; forming a passivation layer including a first contact hole and an open portion, the first contact hole exposing the source electrode and the open portion exposing the pixel electrode, respectively; and forming a data line disposed along a second direction on the passivation layer, the data line connected to the source electrode through the first contact hole and crossing the gate line.
