摘要： PURPOSE:To obtain a wide visual field angle and high contrast by containing nematic liquid crystal whose dielectric anisotropy is positive, photo active material and dichromatic dyes in the liquid crystal layer so that the pitch of its chloesteric state is 1/3 to 1. CONSTITUTION:Material such as 4-(2 methyl butyl)-4' cyano biphenyl is added as photo active material to the nematic liquid crystal whose dielectric anisotropy is positive to make it a cholesteric liquid crystal and further dichromatic dyes are added and mixed at 1.0wt% to the liquid crystal, in the guest-host type liquid crystal display device. This mixture is sealed in the cell having transparent electrodes. At this time, the pitch of the cholesteric state is made 1/3 to 1 the gap of the transparent electrodes. In this way, the display of good contrast which causes phase transition under low voltage is obtained.

摘要： PURPOSE: To obtain high contrast by driving an optical element which has a special optical function material sandwiched between a couple of substrates on AC basis.
CONSTITUTION: The optical function material 6 is inverted in the intensity of transmitted light from the optical element 10 by the inversion of the polarity of an external applied field. The optical function material 6 having said characteristics uses electrochromic material and ferroelectric liquid crystal. A pulse voltage which determines the intensity of light emitted from the optical element 10 is applied to the optical function material 6 at a specific period, and a voltage signal having the polarity opposite to that of the pulse voltage is applied to the optical function material 6 so that the means voltage value within the specific period is zero. Thus, the high contrast is obtained by AC driving although the optical function material 6 is inverted in the intensity of the light from the optical element 10 by the inversion of the polarity of the external applied field.
