Patent abstract
An image display unit is provided for which it is possible to reduce the number of ion plantation and photolithographic processes required to manufacture the device. A gate electrode GT is a laminated structure of a thin bottom layer metal film GMB and a top layer metal film GMT. A top electrode of a storage capacitor Cst is formed of the bottom layer metal film GMB and ion implantation for the top electrode is performed at the same time as the ion implantation of source-drain electrodes. The gate electrode of a PMOSTFT of the device is also formed with the bottom layer metal GMB, and the ion implantation for threshold adjustment is performed by using the same resist.
