Abstract
There is provided a data signal line drive circuit which, when displaying a video signal composed of multiple display frames, drives in at least one of the display frames so as to produce a less-than-grayscale-level display frame where a data signal fed to the data signal lines contains a signal less than a grayscale level represented by the video signal. Thus, a data-hold-type display, a driver device for the display, a display method for the display are provided which is capable of preventing display quality degradation due to afterimages observable in moving image displays without reducing screen brightness.
