The present invention discloses a method for manufacturing a fringe field switching mode liquid crystal display device. Here, a gate bus line has a double layer structure of an ITO layer and an opaque metal layer, and thus the gate bus line and a counter electrode region where a counter electrode is formed are formed at the same time. In addition, a data bus line has a double layer structure of the ITO layer and the opaque metal layer, and thus the data bus line and a pixel electrode region where a pixel electrode is formed are formed at the same time. A polyimide layer is employed as an electrode insulating layer formed between the pixel electrode and the counter electrode.
