Abstract

To provide a high-quality liquid crystal display device that does not produce image sticking and that can realize high response speed, a third electrode is provided that is different from a common electrode or a pixel electrode, and a voltage applied to the third electrode is varied within one frame period to drive a liquid crystal using a strong electric field and a uniform horizontal electric field in an initial stage within one frame period, while driving the liquid crystal only with the uniform horizontal electric field in a latter stage within one frame period.
