Abstract
A liquid crystal display device of the present invention employs a liquid crystal panel of CS control pixel division, and is configured such that two adjacent pixel rows share one retention capacitor wire, and two adjacent scanning signal lines are simultaneously selected. In a case where two pixels ((Pn+1) and (Pn+2)) which are adjacent along a scanning direction but are not simultaneously selected are to have an identical predetermined luminance in two frames, a first signal potential is written to one pixel (Pn+1) in one of the two frames and a second signal potential having a polarity identical to that of the first signal potential is written to the other pixel (Pn+2) in the other of the two frames, the first and second signal potentials are different from each other. The present invention makes it possible to suppress transverse lines of display unevenness which occur in the liquid crystal display device.
