Forming method of liquid crystal layer using ink jet system

A fabricating method of an array substrate of a liquid crystal display device, comprising:

• forming a common electrode on a substrate,
• forming a gate line disposed along a first direction and a common line parallel to the gate line, the common line spaced apart from the gate line and contacting the common electrode;
• 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.
