Abstract: Disclosed are a liquid crystal display device which reduces the number of masks and improves an aperture ratio, and a method for fabricating the same. The liquid crystal display device includes gate and data lines perpendicularly intersecting on a substrate having pixel and pad parts; a thin film transistor on the substrate at the intersection of the gate and data lines; a pixel electrode on the substrate at the pixel part and connected directly to a drain electrode of the thin film transistor; an insulating film on the overall surface of the substrate including the pixel electrode and the thin film transistor; an organic film on the insulating film over the thin film transistor and the data line; and a common electrode of slit shapes overlapping the pixel electrode such that the insulating film is interposed between the common electrode and the pixel electrode.
