In a hold-type display device which holds a display of gradations for 1 frame period, each pixel displays 1 gradation required by an external system by displaying a plurality of gradations within 1 frame period, and the plurality of gradations within 1 frame period is displayed based on voltages which are generated by gradation voltage generation circuits which differ from each other.
