Zusammenfassung:	There is provided a liquid crystal display device that can easily suppress color variation, even if there is a difference in white tolerance of the backlight. The liquid crystal display device includes a liquid crystal display panel to which an image signal is input, and a backlight provided on one side of the liquid crystal display panel, using a light emitting diode as a light source of the backlight. Information about the white tolerance of the light source using the light emitting diode, which indicates one rank of plural ranks assigned to the white tolerance, is clearly indicated in a portion of the backlight. The information is input to an image quality processing circuit in order to correct gamma characteristics of the image signal according to the information.
