An object of the invention is to improve the moving-picture quality of an active matrix type liquid crystal display apparatus. The apparatus comprises liquid crystal pixels disposed in a matrix configuration, a line drive circuit sequentially scanning each line of the pixels at every frame repeating with a predetermined frequency, and a column drive circuit writing an image signal into the pixels in sync with the sequential scanning. The frame is divided into a preceding and following sub-frame. The line drive circuit scans sequentially for the preceding and a following sub-frame. The column drive circuit writes an image signal originally assigned to a frame into the pixels for the preceding sub-frame, and then writes an image signal for adjusting the image quality into the pixels for the following sub-frame. The image signal for adjusting the image quality is obtained by operating the image signal assigned to the frame and an image signal assigned to the next frame.
