Abstract:
1. A method of manufacturing a display substrate, the method comprising: forming a gate metallic layer on a base substrate; patterning the gate metallic layer using a first photoresist pattern as an etching mask to form a gate pattern including a gate conductor, a gate electrode of a switching element and a storage common electrode through patterning the gate layer; forming a source metallic layer on the base substrate including the gate pattern, the source metallic layer including a first lower layer of molybdenum or a molybdenum alloy and a first upper layer of aluminum or an aluminum alloy; patterning the source metallic layer using a second photoresist pattern to form a source pattern including a source conductor crossing the gate conductor, a source electrode and a drain electrode of the switching element; and forming a pixel electrode electrically connected to the drain electrode using a third photoresist pattern.
