PROBLEM TO BE SOLVED: To provide a liquid crystal display device in which the occurrence of multi-contour in the display of a moving image can be reduced as much as possible by changing contents of backlight scanning processing in accordance with an executed double speed drive mode. SOLUTION: When an interpolation image insertion mode is executed in which an interpolation image signal generated on the basis of two or more continuous frame images is inserted between frames and written into a liquid crystal panel, the cycle of the execution of the intermittent lighting operation in the backlight scanning processing is made coincident to the cycle of the vertical synchronization signal. When an overlapped image output mode is executed in which the same frame image is written into the liquid crystal panel (n) times in a row, the cycle of the execution of the intermittent lighting operation in the backlight scanning operation is made longer than the cycle of the vertical synchronization signal (or the backlight scanning operation is made invalid).
