Abstract:
1. A fabricating method of a liquid crystal display device comprising: performing a first mask process comprising forming a first conductive pattern group having a gate line on a substrate, a gate electrode connected to the gate line, a common line formed in parallel to the gate line and a common electrode connected to the common line; forming a gate insulating film overlying the first conductive pattern group; a second mask process comprising forming a second conductive pattern group having a data line crossing the gate line on the gate insulating film and defining a pixel area, a source electrode connected with the data line, and a drain electrode opposite to the source electrode, and a semiconductor pattern forming a channel between the source electrode and the drain electrode; forming a passivation film to cover the second conductive pattern group and the semiconductor pattern; a third mask process comprising forming a pattern hole perforating the passivation film and the gate insulating film, and a third conductive pattern group within a border defined by the passivation film within the pattern hole and having a pixel electrode constituting a horizontal electric field with the common electrode, and wherein the pixel electrode comprises a first conductive layer and a second conductive layer overlying the first conductive layer.
