1. A liquid crystal display panel comprising:

  • a thin film transistor (TFT) substrate including a plurality of touch electrodes, a plurality of subpixels respectively including a plurality of pixel electrodes, and a plurality of switching transistors;

    a color filter (CF) substrate including a plurality of common electrodes and a plurality of color filters respectively corresponding to the plurality of subpixels; and

    a liquid crystal layer disposed between the TFT substrate and the CF substrate, and liquid crystal being in the liquid crystal layer,wherein each of the plurality of touch electrodes comprises;

    a touch line connected in common to two or more adjacent subpixels which are disposed on one horizontal line; and

    a touch electrode line disposed to overlap a data line included in the TFT substrate and electrically connected to two or more adjacent touch lines which are along the data line,wherein the touch line comprises;

    a main touch line extending to a subpixel adjacent thereto; and

    a unit touch line branching from the main touch line,wherein the unit touch line is disposed along an outer portion of the pixel electrode included in each of the two or more adjacent subpixels, andwherein the main touch line and the unit touch line in each of the two or more adjacent subpixels form enclosed rectangular rings overlapping the two or more adjacent subpixels, respectively.
