Abstract
Provided are a liquid crystal display device and a drive method thereof, capable of promptly making an afterimage, which is visually recognized at refresh time, visually unrecognizable and reducing power consumption during and after a shift to a target refresh rate. At pause drive time until a target refresh rate is reached, a refresh is performed in divided periods of a first refresh period for performing a refresh at least twice, and a second refresh period for performing a refresh while increasing the number of frames in a non-refresh period from a refresh rate at the end of the first refresh period until the refresh rate becomes the target refresh rate, and the second refresh period is finished when the refresh rate in the second refresh period reaches the target refresh rate, and the pause drive is continued at the target refresh rate.
