Abstract
In a liquid crystal display device, it is determined whether or not image data inputted from the outside has changed from image data of the previous frame by comparing those image data with respect to each line. As a result, when it is determined that the image data has changed, an entire screen is not rewritten, but image data from a top of a screen as a fixed position to a last line with the image data having changed are read from a frame memory and written into a pixel formation portion. Accordingly, of the screen for one frame, a screen from a top thereof to the last line where the image change has been detected is updated, and on subsequent lines, an image of the previous frame is continuously displayed.
