Abstract
The present invention includes: a liquid crystal panelon which is formed a matrix of a plurality of image elements; a correction circuitthat receives a video data gradation signal input, generates a correction signal for correcting luminance using a relationship defined by the gradation level from an input gradation for an (N−1)-th frame and the gradation level from an input gradation for an N-th frame, and corrects the input gradation signal for the N-th frame using the correction signal; a data drivergenerating a write potential based on the corrected input gradation signal for the N-th frame and applies the potential to an image element; and a scan driver selecting an image element to which the write potential is applied.
