ABSTRACT:
In a liquid crystal display device, MIM type nonlinear resistive swiching elements are connected to pixel electroes, respectively, counter electrodes are arranged to oppose the pixel electrodes and, a liquid crystal layer having a threshould voltage Vth (V) and a saturation voltage Vsat (V) is arranged between the pixel electrodes and the counter electrodes. A voltage having a voltage waveform constituted by a select period in which the signal voltage is applied and a nonselect period in which the signal voltage is held is generated between said electrodes, and an absolute value Vb (V) of the voltage applied between said electrodes during the nonselect period satisfies a relation of:
