Abstract: A display device includes a plurality of pixels arranged in a column direction and a row direction, a plurality of data lines and a data driving part configured to apply data signals to the data lines. The data lines are connected with one of the pixels of a k-th column (‘k’ is a natural number) and one of the pixels of a (k+1)-th column in an odd-numbered row. The data lines are connected with one of the pixels of a (k+1)-th column and one of the pixels of a (k+2)-th column in an even-numbered row. As a result, a pseudo dot inversion drive pattern may be implemented while driving the data lines in accordance with a columnar polarity inversion scheme.
