Liquid crystal display device with matrix electrode structure

A liquid crystal display device comprising:

• a liquid crystal display panel having n×m pixels constituted by a matrix electrode structure having n stripes of scanning electrodes and m stripes of signal electrodes, and a liquid crystal disposed between the scanning electrodes and the signal electrodes, the liquid crystal being an anti-ferroelectric liquid crystal that changes states between an anti-ferroelectric state and a positive-or-negative ferroelectric state according to voltages imposed thereon;
• scanning electrode driving means for imposing scanning voltages sequentially on the scanning electrodes, the means providing a selecting period during which picture images are written on the pixels, a holding period during which the picture images are maintained by a holding voltage, a polarity of which is reversed at least one time, and an eliminating period during which the picture images are eliminated by an eliminating voltage;
• and
• signal electrode driving means for imposing signal voltages representing the picture images sequentially on the signal electrodes in synchronism with the scanning voltages, thereby displaying picture images on the display panel, wherein:
• the eliminating voltage includes a pulse voltage having a polarity opposite to a polarity of the holding voltage immediately preceding the eliminating period;
• and
• the eliminating voltage eliminates the picture images by changing the states of the anti-ferroelectric liquid crystal from the positive-or-negative ferroelectric state to the anti-ferroelectric state.
