Claim:
An apparatus for driving a liquid crystal display device, comprising: a liquid crystal panel comprising an image display including a plurality of data lines, a plurality of gate lines, a plurality of pixels having odd-column pixels each of which is connected to a first side of one of the data lines and connected to an associated odd gate line, and even-column pixels each of which is connected to a second side of one of the data lines and connected to an associated even gate lines; a gate driver that provides different gate pulses to the odd-column pixels than to the even-column pixels, wherein the gate driver provides gate pulses of different widths to the odd-column pixels and the even-column pixels; a plurality of data drivers that provide data voltages having a positive or negative polarity to the data lines; and a timing controller that controls the gate driver and the data driver, wherein the timing controller repeatedly generates first and third gate shift clocks having a first width and a first phase delay for one horizontal period, repeatedly generates second and fourth gate shift clocks having a second width different from the first width and a second phase delay for one horizontal period, and supplies the first to fourth gate shift clocks to the gate driver; wherein the gate driver comprises a first gate driver circuit that provides gate pulses, which have the first width, to the gate lines connected to the odd-column pixels using the first and the third gate shift clocks; and a second gate driver circuit that provides gate pulses, which have the second width, to the gate lines connected to the even-column pixels using the second and the fourth gate shift clocks; wherein the first width of the gate pulses provided to the odd-column pixels is wider than the second width of the gate pulses provided to the even-column pixels; and wherein the ratio of the first width to the second width is about 10:7.
