Abstract
The present invention provides an image display device capable of appropriately controlling the luminance of its backlight even with a frame memory having a size larger than the size of the active area. The image display device of the present invention includes: an image display panel configured to display an image; a backlight configured to illuminate the image display panel; a frame memory having a size larger than the size of an active area of the image display panel; and a luminance determiner configured to determine the luminance of the backlight based on an image data set of a computational area among image data sets stored in the frame memory, the computational area being at least part of the active area.
