According to one embodiment, an image display device includes an image-signal input module, an image-quality corrector, a light emitter, and a liquid-crystal display module. The image-signal input module receives an image signal. The image-quality corrector performs, based on an image-quality correction amount, an image-quality correction process on the image signal. The light emitter includes a plurality of light sources for emitting light. The liquid-crystal display module modulates, among light emitted from the light sources, light transmitted through the liquid crystal to display an image according to the image signal subjected to the image-quality correction process. The light emitter emits the light according to the image signal with less image-quality correction amount than that of the image signal subjected to the image-quality correction process.
