发明名称 LIQUID CRYSTAL DEVICE
摘要 PROBLEM TO BE SOLVED: To excellently drive an anti-ferroelectric liquid crystal element of which the ferroelectric liquid crystal phase state has memory ability in the state without electric field. SOLUTION: For a scanning selection period TS, the pixels of a selected line are brought into a predetermined optical state by impressing not only a scanning selection signal but also an information signal according to display information, and for the following holding period TH, reversal from a ferroelectric liquid crystal phase state to an anti-ferroelectric liquid crystal phase state is promoted by applying an alternating voltage of±Vh on scanning electrodes and applying an alternating voltage on the liquid crystal layer of the pixel of the line, and all the pixels of the line are reset to the anti- ferroelectric liquid crystal phase state by applying only an information signal voltage on the liquid crystal layer of the pixels of the line for the following frame reset period TR.
