Abstract

PURPOSE: To obtain good visibility, durability and arrangement stability by immersing substrates into a DMOAP (N,N-dimethyl-N-octadecyl-3-aminopropylmethoxyl chloride) soln. or bringing the same into contact with said liquid, then washing away the excess DMOAP with water and forming only the min. monomolecular W several molecular film necessary for vertical orientation.
CONSTITUTION: The substrates formed with transparent electrodes 2 and insulating films 3 is immersed into an aq. soln. (more preferably an aq. soln. of pure water) of the DMOAP. The concn. of the DMOAP in this stage is adequately 0.1W10g/l and the liquid temp. as immersion conditions is a room temp. or higher temp. The immersion time of 10secW30min is practicable. The above-mentioned immersion is preferably executed by stirring the aq. soln. by a pump, stirrer or the like to create water flow or vertically oscillating the transparent substrates 1 or applying ultrasonic waves to a container contg. the aq. soln. to finely oscillate the soln. The substrates are thereafter pulled up and are cleaned with the water to wash away the excess DMOAP sticking to the substrates. After the substrates are cleaned with an org. solvent having compatibility with water, the substrates are immersed in the heated vapor of the org. solvent and is dried by which the substrates are subjected to a heating treatment.
