1. A liquid crystal display device comprising:

  • a substrate defined into a plurality of pixels;

    a plurality of data lines arranged in a first direction on the substrate to divide the pixels two by two;

    a plurality of gate lines arranged on the substrate in a second direction crossing the first direction;

    thin film transistors disposed on the pixels, to be electrically connected to the respective gate lines and data lines;

    pixel electrodes disposed on the pixels, to be electrically connected to the respective thin film transistors;

    compensation electrodes overlapped with the pixel electrodes adjacent to the respective gate lines in the center of an insulation film, to reduce parasitic capacitances between the pixel electrodes and the gate lines; and

    common lines, parallel with the data lines between the pixels which are divided in two by the data lines, each including storage electrode portions which are overlapped with the respective pixel electrodes in the center of the insulation film and form storage capacitors,wherein the common line is crossed with the plurality of gate lines,wherein the compensation electrode is disposed parallel to the gate line,wherein the storage electrode portion is disposed parallel to the data line, andwherein each of the thin film transistors of the gate lines which are disposed in both sides of pixel electrodes on the same row and each of the thin film transistors is alternately connected to the pixel electrodes,wherein the common line is disposed between two pixels divided by the data lines and each of storage electrodes protruded from the common line is disposed at a left pixel and a right pixel of two pixels, andwherein the storage electrodes are parallel with the common line.
