Abstract

Provided are a liquid crystal display device and a drive method thereof, capable of promptly making an afterimage, which is visually recognized during pause drive, visually unrecognizable while suppressing power consumption. When updated image data is transmitted, a first refresh is performed by used of this image data, and a refresh pauses based on Ref_int just in the next two-frame period. Then, the second and third refreshes are consecutively performed, and a refresh pause is repeated until the next updated image data is transmitted. In this case, since a refresh can be performed three times in a short period after reception of the updated image data, it is possible to make liquid crystal molecules oriented in a direction corresponding to an applied voltage in a short time and make an afterimage visually unrecognizable.
