Abstract
A liquid crystal display device comprises: a liquid crystal module including liquid crystal display panel having a plurality of liquid crystal picture elements arranged in a matrix form, and driving circuits for applying driving signals to signal electrodes and to scanning electrodes of the liquid crystal display panel, respectively; a control circuit for controlling operations of the liquid crystal module; and a means for inverting polarity of a voltage to be applied to a liquid crystal layer by generating a control signal M' having a period m.tau. which signal inverts the polarity of the voltage to be applied to the liquid crystal layer whenever a clock signal having a period .tau. is counted a predetermined number m/2. However, if a period of a frame frequency is n.tau. and an arbitrary integer is L,
