Abstract
A liquid crystal display device includes a first substrate, a first thin film transistor formed on the first substrate, a pixel electrode and a common electrode formed above the first thin film transistor of the first substrate, a liquid crystal layer formed above the pixel electrode and the common electrode, a second substrate provided above the pixel electrode and the common electrode via the liquid crystal layer, a shield electrode formed on a substantially entire surface of the liquid crystal layer side of the second substrate, a switch device being electrically connected to the shield electrode and the interconnection, wherein the switch device is turned on when a potential of the shield electrode is larger than the specific potential of the interconnection and a difference between the potential of the shield electrode and the specific potential of the interconnection is larger than predetermined potential.
