An etchant composite for forming a metal wiring and a method for patterning a conductive film and for manufacturing a flat panel display using the etchant composite are provided to extend the lifetime of etchant by lowering the vocalization of the oxidizer. A manufacturing method of a flat panel display using the etchant composite for forming a metal wiring comprises a substrate(100). A gate wiring and a gate electrode(110) are formed by forming a first conductive film on the substrate and patterning. A semiconductor layer is formed on the top of the substrate in which the gate wiring is formed. After forming a second conductive film on the semiconductor layer and patterning, and then a source electrode(140a) and a drain electrode(140b) are formed. A protective layer(150) has a contact hole(CNT) exposing one part of the drain electrode is built up. A third conductive film is electrically connected with the drain electrode through a contact hole and located on the protective layer. The third conductive film is patterned to form a pixel electrode(160).
