Abstract: An exemplary interconnected structure for transferring a voltage signal to a thin film transistor (TFT) array substrate includes a first metal layer (310), a second metal layer (320) isolated from the first metal layer and a conductive layer (340) isolated from the second metal layer. The first metal layer is electrically connected to the conductive layer via at least one first contact hole (351, 352) thereby obtaining a first contacting area between the first metal layer and the conductive layer. The second metal layer is electrically connected to the conductive layer via at least one second contact hole (353, 354) thereby obtaining a second contacting area between the second metal layer and the conductive layer. A radio of the sum of the first contacting area and the second contacting area to the voltage value of the voltage signal is equal to or greater than 0.233 ?m2/mv.
