Therefore, a capacitor can be provided to a liquid crystal element if a pixel does not include a wiring for a storage capacitor. An antistatic electrode is provided on the outer side of a color filter substrate and the capacitance between the antistatic electrode and the common electrode is utilized, so that the liquid crystal display device can be used as a touch panel.
