METAL LINE AND METHOD OF THE SAME AND DISPLAY SUBSTRATE HAVING THE SAME

摘要

A metal wiring, a method for manufacturing the same, and a display substrate having the same are provided to improve the electrical characteristic of a display device, by forming the metal wiring of triple metal layers where a middle layer is shield by a lower layer and an upper layer. A first conductive material layer(130) is formed above a substrate(110). A second conductive material layer(120) is formed on a lower surface of the first conductive material layer, and shields the lower surface of the first conductive material layer. A third conductive material layer(140) is formed on an upper surface of the first conductive material layer, and shields the upper surface of the first conductive material layer.
