摘要： PROBLEM TO BE SOLVED: To provide an active matrix liquid crystal display device permitting to display a high quality moving picture and permitting also low power consumption. SOLUTION: In the active matrix liquid crystal display device, one frame period is divided into plural sub-frame periods, and the pixels of all the lines to be scanned during the sub-frame periods are selected in a batch, and in synchronization with this batch selection, an erase signal for uniformalizing the pixel potentials is written in the pixels selected in a batch. Moreover, since the device has a function of correcting and converting the original picture signal levels in the direction in which a level difference from the erase signal level increases, and writes this converted signal in each pixel as a picture signal, the response speed of the liquid crystal is accelerated, and the luminance of the liquid crystal panel is improved. Further, since the erase signal is written in a batch in the pixels of all the lines to be scanned during the sub-frame periods, the device can be made to operate at a driving frequency equivalent to conventional one.
