PROBLEM TO BE SOLVED: To provide an image display device and method capable of adjusting brightness, which is capable of adjusting the power consumption of a backlight module and the brightness to reduce power consumption. SOLUTION: An image wherein the brightness of backlight and contrast of image data are adjusted is displayed by a brightness determining unit 220 that determines the brightness of image data applied from outside so as to output a backlight selection signal and a contrast selection signal, a backlight control unit 231 that is connected to the brightness determining unit and outputs a backlight driving voltage for supplying backlight with brightness corresponding to the backlight selection signal, and a contrast control unit 241 that is connected to the brightness determining unit and outputs an image output signal for outputting an image of which the contrast is adjusted to correspond to the contrast selection signal.
