Abstract
A driving method for a liquid crystal device of the type comprising a matrix electrode structure having scanning lines and data lines, and a ferroelectric liquid crystal. In the driving method, (a) in a first period, a scanning selection signal is applied to a scanning line and applying an information signal is applied to a data line in synchronism with the scanning selection signal, and (b) in a second period, an alternating auxiliary signal is applied to the data line.
