Abstract
An image display device includes: a color gamut determining unit configured to determine a color gamut of pixels constituting an image; an image separating unit configured to separate the image into a low chroma image component and a high chroma image component based on a color gamut determination result; and a display unit configured to divide one frame period into subframe periods and temporally separate the low chroma image component and the high chroma image component in each subframe period to form an image. A backlight driving unit causes a broadband light source to emit light when the low chroma image component is being displayed and causes a narrowband light source to emit light when the high chroma image component is being displayed.
