    BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid crystal display device, and more particularly, to a liquid crystal display device adopting a honeycomb-like pixel structure, which is excellent in color realization characteristics and capable of displaying a graphic screen in an oblique form.
    The liquid crystal display device is composed of a color filter substrate expressing color by subtracting mixing of RGB, a TFT substrate for controlling each pixel, and a liquid crystal injected between the color filter substrate and the TFT substrate. The color filter substrate of the liquid crystal display device includes a plurality of pixels arranged in a matrix form of columns and rows. Each pixel consisted of a combination of red, green and blue dots.
    Representative methods for arranging the pixels include a triangular array, a stripe array, and a mosaic array. The vertical stripe arrangement method as shown in FIG. 1 is mainly used for O / A.
    Referring to FIG. 1, a plurality of gate lines G11, G12, G13,..., Arranged at a predetermined interval from each other in a vertical stripe array method are formed to extend in a column direction and are insulated from each other. The plurality of data lines D11, D12, D13, ... arranged at a predetermined interval from each other extend in a row direction to intersect the gate line, and are insulated from each other.
    In addition, each of the R, G, and B dots RD, GD, and BD are formed in the pixel areas PS11 to PS13 defined in the data lines D11, D12, ..., and the gate lines G11, G12, ..., respectively. Arranged to constitute one pixel.

The driving TFT switching elements T11, T12, and T13 are arranged respectively. Therefore, each R, G, B dot RD, GD, BD is arranged in one pixel area PS11, PS12, PS13, and each R, G, B dot is placed in each pixel area PS11-PS13. TFTs T11 to T13 for driving are arranged one by one, respectively.
    Referring to the pixel array structure of FIG. 1, the R, G, and B dots RD, GD, and BD constituting one pixel are arranged in a vertical direction, respectively. That is, each of the R dots RD, G dots GD, and B dots BD is arranged in a straight line along the data line in the row direction.
    The liquid crystal display device having the above vertical stripe array structure is a pixel array structure suitable for O / A, and its color implementation characteristics are not suitable for A / V as compared with the triangle array structure.
    The triangle array structure of FIG. 2 is used in the liquid crystal display device as a pixel array structure for improving color implementation characteristics. In the liquid crystal display of FIG. 2, a plurality of gate lines G21, G22, G23,... Which are arranged at a predetermined interval from each other are elongated in the column direction, and are insulated from each other. In addition, a plurality of data lines D21, D22, D23, ... arranged at predetermined intervals are insulated from each other so as to cross the gate line, and are twisted in a row direction, that is, in a zig-zag form. Are arranged.
    In addition, each of the pixel areas PS21 to PS23 formed by the data lines D21, D22, ..., and the gate lines G21, G22, ... has R, G, and B dots RD, GD, BD. ) Are arranged in triangle form.
    Dots in which gates and source or drain electrodes are connected to gate lines and data lines at portions where the data lines D21, D22,..., And gate lines G21, G22,... The driving TFT switching elements T21-T23 are arranged. Also in the liquid crystal display of FIG. 2, as in FIG. 1, each of the R, G, and B dots RD, GD, and BD are arranged in one pixel area PS21, PS22, PS23, and each pixel area PS21-. In PS23, TFTs T21-T23 for driving each of the R, G, and B dots are arranged one by one.
    The liquid crystal display device having the triangular pixel array structure of FIG. 2 has an advantage of superior color implementation characteristics as compared to the stripe pixel array structure of FIG. 1.
    However, in the case of the liquid crystal display device having the triangle-shaped pixel array structure as described above, since data lines are formed by being zigzag-90 degrees, data open defects are not easy to occur and the resistance of the data lines is increased. There was a problem.
