PURPOSE:To prevent monostabilization of liquid crystal molecules at the driving of an element and to improve the bistability thereof by forming one surface, which contacts the ferroelectric liquid crystal layer, of two sheets of electrode substrates sandwiching the ferroelectric liquid crystal layer so as to have electrical conductivity. CONSTITUTION:Since an insulating layer 6 is not formed on the upper substrate side the upper substrate side has electrical conductivity, then, the positive charge deviated near the upper substrate is annihilated by impressing a DC electric field in the direction of negative the electric field by the spontaneous polarization of the liquid crystal molecules 5 to the element at the non-display time of the element. The negative charge deviated near the substrate on the opposite side is simultaneously annihilated. Either of the surfaces, which contact the ferroelectric liquid crystal, of two sheets of the electrode substrates sandwiching the ferroelectric liquid crystal layer is formed to have the electrical conductivity. The monostabilization of the liquid crystal molecules by the deviation of the ions of the element is thereby prevented and the bistability of the liquid crystal molecules is improved to a greater extent. |
