Image display device and image display method

An image display device comprising:

• an image-signal input module configured to receive an image signal;
• an image-quality corrector configured to perform, based on an image-quality correction amount, an image-quality correction process for correcting image quality on the image signal received through the image-signal input module;
• a light emitter that includes a plurality of light sources each arranged in one of a plurality of areas, the light emitter being configured to emit light from each of the light sources;
• and
• a liquid-crystal display module configured to modulate, among light emitted from the light sources, light transmitted through a liquid crystal to display an image according to the image signal subjected to the image-quality correction process performed by the image-quality corrector based on the image-quality correction amount, wherein
• the light emitter emits the light from each of the light sources according to the image signal with less image-quality correction amount than the image-quality correction amount of the image signal subjected to the image-quality correction process.
