POLYMER DISPERSION-TYPE LIQUID CRYSTAL DEVICE, AND DRIVE METHOD OF POLYMER DISPERSION-TYPE LIQUID CRYSTAL PANEL

摘要

This polymer dispersion-type liquid crystal device is provided with a pair of transparent substrates, a pair of transparent electrodes disposed between the pair of transparent substrates, a liquid crystal layer comprising a polymer dispersion-type liquid crystal filled between the pair of transparent electrodes, a drive circuit which sets the liquid crystal layer to a non-scattered state or a scattered state application of voltage between the pair of transparent electrodes, and is characterized in that the drive circuit applies between the pair of transparent electrodes a DC voltage that periodically reverses polarity.
