Abstract
PURPOSE:To enable the switching driving of a ferroelectric liquid crystal panel having a particularly large image plane by specifying the capacity of an insulator film and the relations between the capacity and spontaneous polarization of the ferroelectric liquid crystal. CONSTITUTION:The capacity of the insulator film of the ferroelectric liquid crystal element having counter electrodes, the ferroelectric liquid crystal disposed between the electrodes, and the insulator film which is formed on at least either electrode of the counter electrodes and has >=200Angstrom thickness is specified to Ci(nF/cm<2>) and the capacity and spontaneous polarization of the ferroelectric liquid crystal, respectively designated as CLC(nF/cm<2>) and PS(nC/cm<2>), are so specified as to have the relations Ci(nF/cm<2>) >=2.PS(nC/cm<2>)-CLC(nF/cm<2>), more preferably Ci(nF/cm<2>)>=7. PS(nC/cm<2>)-CLC(nF/cm<2>). The practicable use of the large-area display panel is thereby enabled.
