Abstract:
1. A liquid crystal display device comprising: first and second substrates; gate and data lines arranged to cross each other on the first substrate to define a pixel region; a pixel electrode formed in the pixel region; a common electrode forming an electric field together with the pixel electrode and sensing a touch of a user; a light shielding layer formed on the second substrate to shield light leakage to a region other than the pixel region; column spacers formed on the light shielding layer to maintain a cell gap; and a sensing line formed on the column spacers and electrically connected with the common electrode, wherein the common electrode includes a plurality of first common electrodes for sensing only one of a touch position of X axis and a touch position of Y axis and a plurality of second common electrodes for sensing the other one of the touch positions of X axis and Y axis, and the sensing line is not electrically connected with the plurality of second common electrodes but electrically connected with the plurality of first common electrodes, wherein the plurality of second common electrodes are extended from one end portion of the substrate to the other portion of the substrate continuously, wherein the common electrode is formed on the first substrate and the sensing line is formed on the second substrate.
