Abstract
A driving method for a liquid crystal device, which has a first electrode, a second electrode, and a third electrode for trapping ions, includes applying AC signals having the same frequency but whose phases in an amount of time corresponding to a single cycle are shifted relative to each other to the first electrode, the second electrode, and the third electrode, respectively, so that the distribution of an electrical field produced between the first electrode, the second electrode, and the third electrode is scrolled from the first electrode to the third electrode over time.
