There is provided a liquid crystal display. A liquid crystal display panel displays an image. An external light sensor senses a color temperature of external light around the liquid crystal display panel. The output luminance of a backlight is controlled in response to an adjustment dimming signal which is varied according to an input image. A gamma curve adjustment circuit restores an original color of the display image irrespective of a change in the viewing environments by modulating input digital video data based on the color temperature of the external light or a relative maximum white luminance for the adjustment dimming signal. |
