A liquid crystal display (“LCD”) includes a liquid crystal panel having gate lines, data lines and pixels. The pixels are grouped into pixel lines. The LCD further includes a data driver which performs line-inversion driving by applying a data voltage having a positive or a negative polarity to the pixels such that the pixels in each pixel line have a same polarity. The pixel lines are grouped into first and second pixel line groups. A polarity of the pixels in each pixel line of the first pixel line group is the same as a polarity of the pixels in at least one pixel line disposed on an immediately adjacent side thereof. A polarity of the pixels in each pixel line of the second pixel line group is opposite to a polarity of both pixels in pixel lines disposed on two immediately adjacent sides thereof.
