Liquid crystal display panel of line on glass type and method of fabricating the same

A method of fabricating a line on glass type liquid crystal display panel including a picture display part having a plurality of liquid crystal cells, each of which is arranged at each crossing area between gate lines and data lines, and line on glass type signal lines provided at an outer area of the picture display part by a line on glass system to apply driving signals required for driver integrated circuits for driving the gate lines and the data lines and connect the driver integrated circuits to each other, said method comprising the steps of:

• forming a portion of the line on glass type signal lines, along with a gate electrode and gate lines of the thin film transistor, by depositing a gate metal onto a lower substrate and then patterning the gate metal;
• forming an active layer of the thin film transistor by entirely coating a gate insulating film and depositing a semiconductor material and then patterning the gate insulating film and the semiconductor material;
• forming a remaining line portion on glass type signal lines, along with source/drain electrodes and data lines of the thin film transistor, by depositing a source/drain metal and then patterning the source/drain metal;
• defining contact holes for exposing pads of the gate line and the data line, the drain electrode of the thin film transistor and pads of the line on glass type signal lines after entirely coating a protective film;
• and
• forming a pixel electrode connected to the drain electrode and a protective electrode connected to the pads of the gate line and the data line and the pads of the line on glass signal lines by depositing a transparent conductive material and then patterning the transparent conductive material.
