<p>PURPOSE:To obtain a liquid crystal electrooptic device which has a uniform monodomain over a wide range having no defects at all and has further a memory effect and steep threshold value characteristic by subjecting only one substrate of upper and lower substrates to a rubbing treatment. CONSTITUTION:The oriented layer 4 is formed on the surface of the substrate 1 provided with transparent electrodes 2 and an insulating layer 3 consisting of SiO2 by coating 6/9 nylon thereto. The substrate 1 subjected to the rubbing treatment and the substrate 1 provided with the transparent electrodes 2 and the insulating layer 3 consisting of SiO2 are adhered via a spacer 7 and DOBAMBC6 is sealed as a ferroelectric liquid crystal material between the substrate to manufacture the liquid crystal electrooptic device. The monodomain of the smectic phase having no defects at all is obtd. over the side range; at the same time, the memory effect and the steep threshold value characteristic are observed as well.</p> |
