Abstract
An LCD device includes a color filter (CF) substrate, a thin film transistor (TFT) substrate and a liquid crystal layer. The CF substrate includes a first transparent substrate, a CF layer, a black matrix and a shielding layer. The TFT substrate includes a second transparent substrate, a pixel electrode, a common electrode, and an insulating layer disposed between the pixel electrode and the common electrode. A control signal in the form of an AC voltage is provided to the shielding layer of the CF substrate, and a DC common voltage is provided to the common electrode. An alternating electric field is generated between the AC voltage of the control signal of the shielding layer and the DC common voltage of the common electrode to push impurity ions existed in the liquid crystal layer to swing up and down in the liquid crystal layer.
