摘要： 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.

摘要： To realize an increase in an image quality of a liquid crystal display device having a capacitive touch screen, and an increase in a reliability of a contact surface and a connection portion.A capacitive touch screen 50 and a liquid crystal display panel 30 are connected, by the same flexible wiring substrate 70, on an interior side when the touch screen 50 and the liquid crystal display panel 30 are laid one on top of the other. By so doing, a terminal is protected from an exterior, and an increase in a number of components is suppressed. Also, by installing the capacitive touch screen 50 on a color filter substrate 20 side of the liquid crystal display panel 30, a reduction of a contrast is prevented. Furthermore, a capacitive touch screen substrate 51 side is made a contact surface for an input. By so doing, a conductive layer 52 of the capacitive touch screen 50 is prevented from tearing due to an abrasion caused by a contact.
