There is provided a liquid crystal display, including: a backlight having a plurality of light sources; a liquid crystal panel configured to display a video picture in a plurality of illumination regions corresponding to the light sources; an intensity value calculator calculating representative intensity values of the illumination regions based on an input video signal; a weight calculator performing a smoothing process on the representative intensity values by using first weights and to calculate second weights of the illumination regions having values which become larger as smoothed values of the representative intensity values becomes smaller than the representative intensity values; an intensity value corrector correcting the representative intensity values of the illumination regions based on the second weights and performe a smoothing process on corrected intensity values by using the first weights to obtain light source intensity values of the light sources.
