Abstract
An image display deviceincludes: a liquid crystal panelhaving a plurality of pixels; and an overdrive execution sectionconfigured to determine, with respect to each of target pixels for which overdrive is performed among the plurality of pixels of the liquid crystal panel, a gain usage value to be used for the overdrive, based on a predetermined set gain value, and to apply, based on the gain usage value, a liquid-crystal driving voltage to the corresponding target pixel, wherein with respect to a pixel, among the target pixels, for which it is judged that a gradation value in a current frame obtained from the video signal is an intermediate gradation value, the overdrive execution sectionperforms a gain suppressing operation for determining the gain usage value as a value smaller than the set gain value.
