Array substrate for a display panel, method of manufacturing the same, display panel having the same and liquid crystal display device having the same

摘要

An array substrate for a display panel includes a base substrate, a signal-applying module, a first electrode, a second electrode, and a protective layer. The signal-applying module is disposed on the base substrate and includes an output terminal to output a data signal. The first electrode is disposed on the base substrate and electrically connected to the output terminal. The second electrode includes silver (Ag), and is disposed on and electrically connected to the first electrode. The protective layer is disposed on the second electrode to cover a portion of the second electrode. Thus, adhesion of the second electrode to a lower layer may be improved, and yellowishness of the second electrode may be prevented.
