<p>PURPOSE:To obtain a liquid crystal element which can attain two stable orientation states even while an electric field is not impressed thereto by subjecting both substrate surfaces to the same surface treatment to realize through bistability. CONSTITUTION:This liquid crystal element is constituted by forming transparent electrodes on the surfaces of the substrates then forming protective layers over the entire part of the substrates and forming further plural spacers on the protective layers. Two sheets of the substrates of which both surfaces in contact with a ferroelectric liquid crystal are subjected to the same surface treatment are used. The liquid crystal element is formed of two sheets of the substrates subjected to exactly the same surface treatment and the liquid crystal layer is made vertically symmetrical, by which the approximately through bistability of the liquid crystal is realized. The liquid crystal element having the two states of the liquid crystal orientation stable even in the non-impression stage of the electric field is obtd.</p> |
