An image display device includes an image data conversion unit that performs conversion processing of input image data and a display unit that displays a plurality of subframes, in one frame period. In the image data conversion unit, the conversion processing is performed in a manner that, for each pixel, a hue and a saturation of the input image data and a hue and a saturation of driving image data in an HSV color space are held to be respectively equal to each other, color components of the driving image data are set to have the same value when the saturation of the input image data is equal to the minimum saturation, and when the saturation of the input image data is equal to the maximum saturation, the color components of the input image data are multiplied by the same value, and then the input image data is compressed.
