PURPOSE: A liquid crystal display(LCD) device driving method is provided to improve a step response characteristics and a display quality of a dynamic image. CONSTITUTION: A drive circuit for materializing the liquid crystal display device driving method includes a first frame memory(1), a second frame memory(2), a third frame memory(3), an arithmetic unit(4) and a liquid crystal display(5). While the image data inputted to any one of the first frame memory(1), the second frame memory(2) and the third frame memory(3) is being written, image data are read repetitively two times in one vertical synchronization interval from the remaining two memories. When one vertical synchronization interval of the inputted image signal thus ends, the first frame memory(1) in which image data A has been written becomes a read frame memory in the next one vertical synchronization interval, and the next image data B is written in the different second frame memory(2). Subsequently, this operation will be sequentially repeated, consistently, with one frame memory used for image data write and with the remaining two frame memories used for image data read. Thus, the two pieces of image data read from the two frame memories are transferred to an arithmetic unit(4).
