1. A touch sensing type liquid crystal display device, comprising:

  • first and second substrates facing each other;

    a liquid crystal layer between the first and second substrates; and

    an anti-static layer on an outer side of the second substrate,wherein the first substrate includes;

    a plurality of first signal lines;

    a plurality of second signal lines crossing the plurality of first signal lines;

    a plurality of pixel electrodes;

    a plurality of common electrodes;

    a sensing line electrically connected to at least one common electrode of the plurality of common electrodes and extending along at least one of the plurality of first signal lines; and

    a sensing circuit electrically connected to the sensing line, andwherein the sensing circuit detects a change of capacitance between an object and the at least one common electrode of the plurality of common electrodes through the sensing line for sensing a touched position.
