ABSTRACT:
An image line driving circuit has: an n-number of switching elements for sampling a k-number of gradation voltages inputted from outside and then sequentially supplying the gradation voltages to first to (n/k)-th groups of a k-number of image lines; and a shift register circuit for sequentially inputting sampling voltages to first to (n/k)-th groups of a k-number of switching elements to thereby sequentially turn ON the respective groups of a k-number of switching elements. The scanning line driving circuit sequentially supplies selected scanning voltages to an m-number of scanning lines. The image line driving circuit and the scanning line driving circuit are circuits built in a semiconductor chip mounted on the first substrate. A thin-film transistor has a semiconductor layer formed of amorphous silicon. When voltage levels of the k-number of gradation voltages inputted from outside are at 0 to 5V, the selected scanning voltages inputted to the gates of the thin-film transistors are 20V or more.
