Abstract:
1. A liquid crystal display device comprising: a liquid crystal display panel including a plurality of pixels; and a driving circuit for driving each of the pixels, wherein each of the pixels has a pixel electrode and an opposite electrode, wherein the driving circuit changes a driving state of each of the pixels from a positive polarity to a negative polarity or from the negative polarity to the positive polarity in every m (m≧1) frame and performs a phase inversion of the driving state of each of the pixels in every N (N=2m×n, n≧1) frame wherein it is assumed that an image voltage having a potential higher than an opposite voltage applied to the opposite electrode is applied to the pixel electrode in a driving state of the positive polarity and that an image voltage having a potential lower than the opposite voltage applied to the opposite electrode is applied to the pixel electrode in a driving state of the negative polarity, and wherein the driving circuit drives each of the pixels so as to maintain a scanning voltage at a selection voltage for a period that includes a change from an image voltage having an opposite polarity to a polarity of a most recent frame prior to performing the phase inversion to an image voltage having a same polarity as the polarity of the most recent frame prior to the phase inversion.
