a liquid crystal display thin film transistor array includes gate bus lines , drain bus lines electrically isolated from the gate bus lines by a first insulating film , a thin film transistor arranged near the intersection of the gate bus line and the drain bus line , and a pixel electrode made of a transparent conductive film . the thin film transistor includes a gate electrode , a drain electrode , and a source electrode . the pixel electrode is electrically isolated from the drain electrode and the drain bus line by a second insulating film . a contact hole for electrically connecting to the drain bus line is formed in the second insulating film stacked on the drain bus line in a region including the intersection of the gate bus line and the drain bus line . an interconnection redundant film made of the same transparent conductive film as the pixel electrode is formed on the second insulating film so as to cover the contact hole . a method of fabricating this array is also disclosed .
