Abstract
In a liquid crystal display device for performing pause driving, occurrence of flicker is effectively suppressed while an increase in power consumption is suppressed. When an image change determination portion () detects an image change in a period from the previous refresh frame until generation of a predetermined number of times of pause frames, a reversal driving control portion () sets the next frame after a frame where an image change has been detected to a refresh frame where a reversal driving technique is a column-reversal driving. When the image change determination portion () does not detect an image change in the period from the previous refresh frame until generation of the predetermined number of times of pause frames, the reversal driving control portion () sets the next frame after the final pause frame to a refresh frame where a reversal driving technique is a dot-reversal driving.
