Abstract
The surface area occupied by a digital type signal line driver circuit in an image display device is large, and this is an impediment to reducing the size of the display device. A memory circuit within a signal line driver circuit is made common among n signal lines (where n is a natural number greater than or equal to 2). One horizontal scan period is divided into n divisions, and all signal lines can be driven by performing processing with respect to signal lines differing by memory circuit and D/A converter circuit, respectively, during the period of each division. It thus becomes possible to make 1/n as many memory circuits and D/A conversion circuits within the signal line driver circuit as in a conventional example.
