Abstract

A method of fabricating an LCD device is discussed. The method in one embodiment includes: 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 layer, source/drain electrode and a data line through a second mask process which uses one of half-tone and diffraction masks; and forming a transparent conductive material on the substrate provided with the source/drain electrode and forming a pixel electrode through a third mask process.
