ABSTRACT:
A method for manufacturing a liquid crystal display device is disclosed, comprising the following steps: (a) providing a substrate having a transparent electrode layer and a first metal layer, wherein the transparent electrode layer is sandwiched in between the first metal layer and the substrate; (b) defining a patterned area having a thin film diode area and a pixel area by a first mask; (c) forming a first insulating layer and a second metal layer on the patterned area having the thin film diode area and the pixel area in sequence, wherein the first insulating layer is sandwiched in between the second metal layer and the first metal layer; and (d) defining the thin film diode area and the pixel area by a second mask, and removing the second metal layer, the first insulating layer, and the first metal layer on the pixel area to expose the transparent electrode layer.
