Abstract

PURPOSE: To so form the device that the film after coating is smooth and superior in adhesion and withstands high temperature heat treatment like glass sealing by constituting an orientation control layer by the silanol condensate containing a suitable amount of OH in its molecular structure.
CONSTITUTION: Ethyl silicate which forms OH through hydrolysis condensation is dissolved at a concentration of less than 30wt% in a suitable solvent containing water and is allowed to react for about 30 minutes 30 to 3 hours at 20 to 70°C. This coating solution for forming orientation control layer is coated on a substrate with electrodes so as to become about 100 to 3000Å thick and is then heat-treated at temperatures of about 200 to 550°C after drying for about 30 minutes at about 150°C, whereby the orientation control layer composed of the silanol condensate containing 3 to 20wt% of OH is formed. Next, the surface thereof is rubbed in a fixed direction by a suitable cloth, after which a pair of the substrates are opposedly disposed by way of a spacer and liquid crystal is sealed therein.
