<p>PURPOSE:To obtain the liquid crystal element having the stable orientation state of liquid crystal molecules strong to pressure, oscillation and impact by using two-layered oriented films of diagonally vapor deposited SiO changed in vapor deposition directions and forming the surface shape of the oriented films meeting the cone angle specific to the ferroelectric liquid crystal molecules. CONSTITUTION:The oriented films are produced by two stages of the production process. SiO projections 14 formed by diagonal vapor deposition from a 7 deg. direction 12 with respect to a glass substrate 11 with transparent electrodes are further stuck thereon with SiO projections 15 formed by spending the vapor deposition time of half the vapor deposition time of the 1st time from an opposite direction 13 to form the two-layered films of the diagonally vapor deposited SiO. The diagonally vapor deposited films are capable of lowering the pretilt angle and the arranging directions 75, 76 of the liquid crystal molecules near the boundary can be made to coincide with about 22 deg. cone angle by controlling the vapor deposition time of the 2nd time. The ferroelectric liquid crystal element having the layered structure which is strong to pressure and impact and is free from distortion is, therefore, obtd.</p> |
