Abstract
A method for manufacturing a fringe field switching mode liquid crystal display device which can improve productivity by reducing the number of steps in the manufacturing process. In this improved method of manufacture, the gate bus line is formed having a stacked structure of a transparent metal layer and an opaque metal layer. In the formation of the gate bus line, the counter electrode is firstly formed, and the active region is formed to cover the gate bus line. Thereafter, the counter electrode is formed by removing the opaque metal layer on the exposed surface of the counter electrode structure. By this method, the gate bus line and the counter electrode structure are formed at the same time thereby reducing the number of mask processes from six, as required by using the conventional manufacturing method, to five.
