Abstract
A liquid crystal display device is disclosed, which comprises 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.
