Abstract:
To realize an increase in an image quality of a liquid crystal display device having a capacitive touch screen, and an increase in are liability 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.
