An LCD with an integrated touch panel that prevents sensor malfunction by eliminating coupling noises includes an insulating substrate, a plurality of gate lines formed on the insulating substrate so as to extend in a first direction, a plurality of data lines formed in a second direction so as to intersect the plurality of gate lines, a plurality of thin film transistors (TFTs), each formed at an area defined by the gate lines and the data lines, a plurality of sensor lines formed in the same directions as the gate lines and the data lines, and a plurality of dummy lines formed in the same directions as the sensor lines.
