    摘要: Driving is effected by MLA under a condition of L≠M or (M/L·(L+D) )≠N where M represents the total number of row electrodes, L represents the number of simultaneously selected row electrodes, D represents the number of dummy row electrodes and N represents the maximum magnifying power of a column voltage wherein driving is performed at a driving bias ratio which is deviated toward the minimum bias ratio with respect to the optimum bias ratio.
