Abstract
A liquid crystal display (LCD) that includes a plurality of pixels, a switch unit, and a gate line driving unit. Each of the pixels includes a liquid crystal capacitor having a pixel electrode and a common electrode, and the pixels are located at intersections of a plurality of gate lines and a plurality of source lines. The switch unit applies source line driving voltages having levels opposite to a common voltage applied to the common electrode, to the source lines. The gate line driving unit sequentially outputs via gate lines gate line driving voltages to control the source line driving voltages to be applied to the pixel electrodes of the pixels. The common voltage transits from a first level to a second level or vice versa at the boundary between a first half frame and a second half frame. At the first half frame, the switch unit applies the source line driving voltages to only odd-numbered source lines. At the second half frame, the switch unit applies the source line driving voltage to only even-numbered source lines.
