Abstract:
1. An LCD (liquid crystal display) device, comprising: a plurality of pixels each having a liquid crystal capacitor that includes a pixel electrode and a common electrode and being located at the intersections of a plurality of gate lines and a plurality of source lines; a switch unit applying source line driving voltages having levels opposite to a common voltage applied to the common electrode, to the source lines; and a gate line driving unit sequentially outputting via the gate lines gate line driving signals to control the source line driving voltages to be applied to the pixel electrodes of the pixels, wherein the common voltage transits from a first level to a second level or vice versa at a boundary between a first half frame and a second half frame, the gate line driving signals are sequentially activated twice for each frame, and at the first half frame, the switch unit applies the source line driving voltages to only odd-numbered source lines, and at the second half frame, the switch unit applies the source line driving voltages to only even-numbered source lines.
