PROBLEM TO BE SOLVED: To prevent a defect in writing and seizure by making the hysteresis small. SOLUTION: When the impedance observed by applying a voltage to a passivation film 7 along its thickness and the impedance observed by applying a voltage in the reverse direction are different from each other,|Zratio|t/((εL.ρ1 ).(d1 /dL>)) holds, where Zratio is the ratio of the two different impedance values,εL the dielectric constant of liquid crystal 5, (t) a basic pulse interval for driving the liquid crystal element 1,ρ1 the volume resistivity of the passivation film 7, d1 the film thickness of the passivation film 7, and dL the thickness of the liquid crystal 5. Consequently, the hysteresis can be made small. |
