ABSTRACT:
The active matrix substrate of the present invention is an active matrix substrate in which a drain extraction line can be prevented from breaking without a plurality of active elements such as TFT (thin film transistor) elements, MIM (metal-insulator-metal) elements, MOS transistor elements, diodes, and varistors being disposed, and is suited for use in large-size liquid crystal television or a like liquid crystal display device equipped with a large-size liquid crystal display panel. The active matrix substrate of the present invention is an active matrix substrate comprising an active element connected, via a drain extraction line, to a storage capacitor upper electrode, wherein the drain extraction line has at least two routes.
