Abstract: A display panel includes a plurality of pixels which is arranged in a pixel column and a pixel row, a gate line which is connected to pixels in a same pixel row, a first data line which is connected to pixels in a same pixel column, and a second data line which is connected to remaining pixels except for the pixels connected to the first data line among the pixels in the same pixel column. Two odd-numbered pixel rows and two even-numbered pixel rows are alternately driven so that a charge period of the pixel may be extended by 2H. In addition, a kickback difference between the odd-numbered pixel row and the even-numbered pixel row may be decreased so that a display quality may be improved.
