Active devices in a thin film diode (TFD) liquid crystal display (LCD) panel used to control liquid crystal are formed by a metal layer, a transparent conductive layer, and an insulating layer sequentially on a substrate, wherein the metal layer is used as transmitting signal and the transparent conductive layer is used as bottom metal layer of metal-insulator-metal (MIM) thin film diode. The metal layer, the transparent conductive layer, and the insulating layer are defined with desired patterns. Further, a dielectric layer is formed over the substrate, metal layer, the transparent conductive layer, and the insulating layer, and defined to form the locations of electrode terminal and MIM thin film diode by using lithographic process. Next, another transparent conductive layer is formed on the dielectric layer and defined to form a pixel electrode and top metal layer of the MIM thin film diode by using lithographic process.
