Abstract
PURPOSE: To improve the defects of the need for high driving voltage and high power consumption and make the device applicable even to small-sized portable apparatus such as electronic calculators, electronic wristwatches, etc. by applying horizontal orientation treatment comprising vapor deposition of SiO at the specific angle to glass substrates.
CONSTITUTION: In the phase transition type liquid crystal display device using the mixed liquid crystals of P type nematic liquid crystal and cholesteric liquid crystal or chiral nematic liquid crystals, the horizontal oritentation treatment comprising diagonal vapor deposition of SiO at angles of 2 to 20° is applied to its glass substrates. Thereby the voltage at which the liquid crystals transfer from the transparent Grandjean G state to the light scattering and non-transparent focal conic state F and from the F state to the G state is made lower as compared to that of the display device of rubbing orientation treatment and displaying at lower driving voltage is made possible. In addition, this reduces current comsumption as well.
