PURPOSE:To obtain a device having a wide visual field angle and high opening rate by adopting a structure in which electrodes for driving liquid crystals are held by >=2 layers of upper and lower dielectric layers exclusive of the liquid crystal layer for the electrodes for driving liquid crystals and specifying the specific resistance of the liquid crystals to a specific range. CONSTITUTION:The wire-shaped electrodes l, 3, 4 are formed on the inner side of a pair of transparent substrates and orientation control films 5 are applied thereon and are subjected to an orientation treatment. A liquid crystal compsn. is clamped between a pair of the substrates. The bar-shaped liquid crystal molecules 6 are so oriented as to have some angle with the longitudinal direction of the striped electrodes 1, 3, 4 at the time of non-impression of an electric field. Changing of light transmittance by impression of the electric field 9 is made possible by arranging polarizing plates 8 at a prescribed angle 11. The structure in which the electrodes for driving liquid crystals are held by >=2 layers of the upper and lower dielectric layers exclusive of the liquid crystal layer is adopted for the electrodes for driving the liquid crystals. The specific resistance of the liquid crystals is specified to <=1X10<14> to >=1X10<9>OMEGA.cm. The opening rate is increased by specifying the specific resistance of the liquid crystals to <=1X10<14>OMEGA.cm such a manner. |
