Claim One:
1. A liquid crystal display comprising: a liquid-crystal-display device, which includes a color filter substrate and a thin-film-transistor substrate; a display control circuit, which generates an image signal to control display of the liquid-crystal-display device; a backlight device, which is disposed on a rear surface of the liquid-crystal-display device, includes at least one white light emitting diode, and emits planar light from an emission surface; and a light-emitting-diode control circuit that adjusts luminance of the backlight device using a pulse width modulation signal as an output to the white light emitting diode, wherein gradation correction data corresponding to a chromaticity variation due to a duty ratio of the pulse width modulation signal is stored in the display control circuit in advance, wherein the display control circuit determines the gradation correction data corresponding to input image data input to the liquid crystal display, based on the input image data and the duty ratio, and wherein the display control circuit outputs output image data, which is calculated so as to correct the chromaticity variation based on the gradation correction data and the input image data, as the image signal to the liquid-crystal-display device.
