Abstract
An object of the present invention is to provide a liquid crystal display-device with a high degree of light utilization efficiency (a high numerical aperture), and for which a rapid response is possible at high contrast. A liquid crystal display device incorporating at least one compound with optical activity for which the value of the spontaneous polarization is positive, and at least one compound with optical activity for which the value of the spontaneous polarization is negative, and for which the overall spontaneous polarization may be either positive or negative, is prepared, and is then held between substrates which incorporate electrodes.
