Abstract
A process for manufacturing an in-plane switching array of a liquid crystal display. A thin-film transistor including a drain, a source and a data line as well as first and second electrodes are fabricated on a cleaned glass substrate. The source, the drain and the data line comprise the same conductive layer as the second electrode. The conductive layer includes a top aluminum layer and a bottom Cr layer. A photo-resist layer is coated and patterned to expose only the area of the second electrode. The top aluminum layer of the second electrode is then etched away to decrease the thickness. Because of the thinner second electrode, the rubbing process can be uniformly completed. The light leak near the edge of the electrode is reduced without increasing the resistance of the data line.
