Abstract
An adjustment method for active-matrix type liquid crystal display device adjusts the potential differences applied to liquid crystal layers in such a way that black images are displayed in one group of pixels with the same polarity of the potential difference during a single vertical scanning period while halftone images are displayed in another group of pixels with the same polarity of the potential difference during the single vertical scanning period.
