1. An LCD with an integrated touch panel, comprising:
- an insulating substrate;
a plurality of gate lines formed on the insulating substrate so as to extend in a first direction and a plurality of data lines formed in a second direction so as to intersect the 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 data lines; and
, a plurality of dummy lines formed in the same directions as the sensor lines,wherein the plurality of sensor lines includes first and second sensor lines formed in the first and second directions, respectively,wherein the plurality of dummy lines includes a first dummy line formed along the periphery of the insulating substrate and second and third dummy lines formed in the first and second directions, respectively, the first dummy line being connected to the second and third dummy lines, andwherein the first sensor line and the second sensor line are connected to first and second electrodes formed on the insulating substrate.
