摘要： The present invention provides an image display unit, which can be manufactured in shorter time by designing a thin-film transistor, by which it is possible to reduce the number of processes of ion implantation and photolithographic processes. A gate electrode GT is designed in a laminated structure of a thin bottom layer metal film GMB and a top layer metal film GMT, and a top electrode of a storage capacitor Cst is designed to have only the bottom layer metal film GMB. Ion implanter for the bottom electrode of the storage capacitor Cst is passed through the thin bottom layer metal film GMB, and ion implantation is performed at the same time as the ion implantation of source-drain electrodes. The gate electrode of PMOSTFT has also only the bottom layer metal GMB, and the ion implantation for threshold adjustment is performed by using the same resist. By designing the thin-film transistor and the storage capacitor in such structure, one process each can be reduced in the photolithographic process and in the ion implantation process, and an active matrix substrate for an image display unit can be manufactured in shorter time and at lower cost.
