ABSTRACT:
A liquid crystal display device in which the time necessary for luminance to change from application of a different gray-scale voltage exceeds one frame period in relation to the response as a luminance change time of the liquid crystal. The liquid crystal display device includes a signal control circuit for preventing the content of a preceding frame from being displayed as an after-image and preventing also deterioration of image quality. The signal control circuit includes a frame memory for delaying by one frame the first display data inputted from the external device, an arithmetic operation circuit for comparing the second display data stored in the frame memory and delayed by one frame with the first display data, and an addition/subtraction circuit for adding and subtracting correction data outputted by the arithmetic operation circuit to and from the first display data.
