Abstract

See full text

In a display device such as a liquid crystal display device, a large sized display screen is realized under low power consumption. A surface of a source wiring line of a pixel portion employed in an active matrix type liquid crystal display device is processed by way of a plating process operation so as to lower a resistance value of this source wiring line. The source wiring line of the pixel portion is manufactured at a step different from a step for manufacturing a source wiring line of a drive circuit portion. Further, electrodes of a terminal portion are processed by a plating process operation so as to reduce a resistance value thereof.
