An LCD device includes a substrate including an active region and a dummy region; gate and data lines disposed on the substrate crossing each other to define a plurality of pixel regions in the active region; a pixel electrode disposed in each of the plural pixel regions; a common electrode which is patterned in the active region to define common electrode pattern portions, respective common electrode pattern portions and the pixel electrodes each forming an electric field; a first sensing line disposed on the common electrode and electrically connected with the common electrode to sense a user's touch; and at least one dummy electrode disposed in the dummy region adjacent one of the common electrode pattern portions.
