摘要： A liquid crystal display device includes a liquid crystal between a substrate having gate buslines, source buslines, switching elements, pixel electrode array, gate driver, source driver, etc., and a substrate having a counter electrode, etc. In this liquid crystal display device, the gate driver performs simultaneous two-line scanning by applying a scanning signal to two gate buslines simultaneously. The source driver feeds video signals of opposite polarities to adjacent source buslines, respectively. The video signals are inverted every vertical scanning period.
