<p>PURPOSE:To easily form a monodomain of a smectic phase and to obtain a liquid crystal cell having a good contrast by arranging a liquid crystal cell using a smetic liquid crystal of ferro-electricity with a comb-shaped exothermic resistor. CONSTITUTION:The comb-shpaed exothermic resistor composed of In2O3 etc. and an electrode impressing a voltage are formed on two insulating base plates made of a transparent glass respectively, and an insulating film of SiO2 is vapor - deposited on the resistor and the electrode, and then an orientation film is formed on the insulating film with the aid of a horizontal orientation treating agent. The smectic liquid crystal of ferro-electricity such as P- decyloxybenzylidene-p-amino-2-merbutylcinnamate is sealed in a space between the base plates. The monodomain formation of the chiral smectic C phase from an isotropic liquid facilitates by arranging the above-describe heating element, thereby obtaining the liquid crystal cell having an excellent contrast and a good orientation state.</p> |
