Abstract: PURPOSE: A method for fabricating a fringe field driving liquid crystal display(LCD) device is to simplify a manufacturing process and reduce a manufacturing cost. CONSTITUTION: A transparent conductive layer(10) and an opaque metal layer(11) are stacked on a lower substrate and are patterned to form a gate bus line(11a), a counter electrode structure and a gate pad. A gate insulating layer, an amorphous silicon layer and an impurity-doped amorphous silicon layer are stacked to form an active area(13). The opaque metal layer is removed to thereby form a counter electrode(12). An insulating layer is deposited on the resulting structure. The insulating layer is patterned to open a predetermined portion of the gate pad and the active area. A transparent conductive layer and an opaque metal layer are stacked on the insulating layer to thereby form a data bus line, a source/drain electrode and a pixel electrode structure. A passivation layer(18) is deposited and patterned to expose the pixel electrode structure. The opaque metal layer is removed to form a pixel electrode(19).
