Abstract:
1. An image display device, comprising: a plurality of display elements, making up a screen, for modulating light according to image data which is applied while being scanned; and an illuminating section for illuminating the display elements, wherein: when those of said display elements having the same scanning time make up a display element band, said display element band is grouped into display element groups in order of earlier scanning time so that each display element group includes at least one display element band, said illuminating section includes a plurality of illuminating elements grouped, in accordance with the display element groups the illuminating elements illuminate, into illuminating element groups so that each illuminating element group includes at least one illuminating element, and the illuminating elements respectively illuminate the display elements in such a manner that each illuminating element group respectively illuminates a display element group in a second luminance in a period from Time P to Time (P+tb), and illuminates in a first luminance in a period from the Time (P+tb) to Time (P+f), the second luminance being darker than the first luminance, where tb is a predetermined time, f is one vertical period, and the Time P is a time at which a display element band having an earliest scanning time in the display element group the illuminating element group illuminates is scanned.
