Abstract: A liquid crystal display device includes a first substrate, a second substrate and liquid crystal. The first substrate includes pixel electrodes, a peripheral circuit and a dummy wiring. The peripheral circuit and the dummy wiring are provided outside a pixel area in which the pixel electrodes are arranged. The second substrate is opposed to the first substrate through the liquid crystal. The second substrate includes a translucent conductive film that is provided on an opposite side of the second substrate to a side where the liquid crystal is present. The dummy wiring is located on an outer peripheral side of the substrates than the peripheral circuit and is provided independently of the peripheral circuit in terms of circuit. The dummy wiring is grounded outside the first substrate.
