An FFS array substrate and a liquid crystal display device having the same are disclosed. The FFS array substrate includes a substrate, first metal layer, a first insulated layer, a second metal layer, a second insulated layer, a transparent electrode layer, a third insulated layer and a common-electrode layer. The common-electrode layer includes a common-electrode line having a low resistivity and a transparent common electrode. The FFS array substrate ensures the stability of electrical potential on common electrode and enhances the display effect of the liquid crystal display device.
