Abstract: An LCD device includes a plurality of gate lines and data lines cross-arranged on a lower substrate to define a plurality of pixels, a pixel electrode disposed in each of the pixels, a plurality of common electrode blocks pattern-formed that generate an electric field with the pixel electrode and sensing a touch of a user, a plurality of sensing lines, a plurality of pad parts arranged to be separated from each other at predetermined intervals along a corresponding sensing line, and having a line width thicker than the sensing line, and a contact part disposed between a corresponding pad part and a corresponding common electrode block, and electrically connecting a corresponding sensing line and the common electrode block. When the sensing lines are electrically connected to one of the common electrode blocks, the sensing lines are electrically insulated from the other common electrode blocks.
