Abstract
An example control signal generating circuit CTL for controlling the writing into pixels PIX instructs a data signal line drive circuit SD, which is for driving pixels in a non-display area, to write a voltage VB or a voltage VW which are for non-displaying, not only in the first frame but also once in a predetermined number of frames. In other words, the pixels in the display area are refreshed at intervals longer than those in the case of refreshing the pixels in each frame. Thus, even if the mobility of an active element is high and the leak current on the occasion of OFF-state is large, or even if a large amount of electric charge is accumulated because of the photoelectric effect due to the use of a backlight, it is possible to prevent unnecessary displaying on the display area, which is caused because the writing into the pixels in the display area influences on the pixels in the non-display area, and hence it is possible to improve the quality of partial displaying, while restraining the power consumption.
