Filed: 1994-02-16
Abstract: PURPOSE:To obtain superior contrast and visibility with a low driving voltage by forming a large number of orientation areas blocked to micro parts and provided with different orientation regulating power on a substrate surface with which liquid crystal is brought into contact. CONSTITUTION:A large number of orientation areas blocked to the micro parts and provided with different orientation regulating power is formed on the substrate surface with which the liquid crystal is brought into contact. A liquid crystal material is sealed in a sandwich cell comprised by using a substrate to which orientation treatment is applied, and when a voltage is applied between counter electrodes, a liquid crystal molecule is arranged in a direction perpendicular to the electrode when the dielectric constant anisotropy of the liquid crystal is positive. When a dichroic pigment in the liquid crystal arranged in the perpendicular direction shows a positive type one, a transparent state is displayed in a state where the voltage is applied. Also, when the dichroic pigment in the liquid crystal arranged in a parallel direction shows a negative type one, the transparent state is displayed in a state where the voltage is applied. In such a way, switching in which light can be absorbed in an initial orientating state and the transparent state can be obtained with the low driving voltage can be performed.
