LIQUID CRYSTAL DISPLAY DEVICE

摘要

A pixel includes a first and a second sub-pixel and a plurality of auxiliary capacity trunks independent from one another. Each of the auxiliary capacity trunks is electrically connected via an auxiliary capacity wire to one of the auxiliary capacity opposing electrodes of the first and the second sub-pixel. The vertical scan period of the input video signal is divided into at least two sub-frames. In each of the sub-frames, a display signal voltage is written into each pixel. Two vertical scan periods in which the input video signals are continuous contain a sequence of two continuous sub-frames where a display signal voltage is written with the same polarity and a sub-frame where the polarity of the display signal voltage is inversed. The auxiliary capacity opposing voltage includes, in each of the sub-frames, a first waveform vibrating with a first cycle of the horizontal scan period multiplied by an integer not smaller than 2 and a second waveform in which an effective value of the auxiliary capacity opposing voltage is set to a predetermined constant value for each vertical scan period of a predetermined number of continuous input video signals. Moreover, the first waveform has a phase different by 180 degrees between the sub-frames having a polarity and an inversed polarity.
