LIQUID CRYSTAL DISPLAY Without the need of a data signal of high frequency such as a horizontal scanning frequency, the polarity of data signal applied to one pixel can be inverted to the polarity of data signal applied to pixels horizontally and vertically adjacent to the one pixel so that a flicker cannot be recognized by an observer. A first data signal is applied to every other column conductor of a plurality of column conductors and a second data signal is applied to remaining column conductors. The polarity of the first data signal is inverted to that of the second data signal. In one mode of the invention, the pixels in the same row are connected to the same row, and the pixels in one column are alternately connected to one column conductor to which the first data signal is applied and to the other column conductor to which the second data signal is applied. The pixels in a column adjacent to the above one column are alternately connected to the above one and the other column conductors with one pixel being shifted in the column direction with respect to the pixels in the above one column. In another mode of the invention, the pixels in each row are alternately connected to adjacent two row conductors, and the pixels in each column are alternately connected to one column conductor to which the first data signal is applied and to the other column conductor to which the second data signal is applied. In both modes, the frequency of the first and second data signals can be made a flame frequency. If the number of row conductors are 550, the frequency of data signal is 550 times smaller than prior art.
