Patent ID: 8343787

Claim:
A method of fabricating a liquid crystal display device, the method comprising the steps of: forming a gate electrode and a gate pad on a substrate, which is defined into a display area corresponding to pixel regions and a non-display area corresponding to pad regions, through a first mask process; sequentially stacking a gate insulation film, an amorphous silicon layer, an impurity-doped amorphous silicon layer and a metal film on the substrate provided with the gate electrode and then forming an active region, a source/drain electrode and a data line through a second mask process which uses one of half-tone and diffraction masks; forming a transparent conductive material on the substrate provided with the source/drain electrode and forming a pixel electrode through a third mask process; forming an organic film on the substrate provided with the pixel electrode and performing an imprinting process to form first and second depressions which are respectively positioned in the pixel and pad regions; performing a second etch process for the organic film provided with the first and second depressions to form a contact hole in the pad region; sequentially forming a common metal film and a photo resist film on the substrate provided with the contact hole and performing one of etching and ashing processes to expose the common metal film on all the regions except the first depressions and the contact hole; and performing an etching process, which uses the remaining photo resist film within the first depression and contact hole as a mask, to form a common electrode on the pixel region and a gate contact pad on the pad region.
