Abstract:
A liquid crystal display apparatus according to the present invention includes: a liquid crystal panel; a backlight provided on a rear face of the liquid crystal panel; a detector which detects RGB output light levels of the backlight; a first controller which controls backlight current for driving the backlight so that a prescribed luminance is attained based on the RGB output light levels detected by the detector; and a second controller which controls display signals supplied to the liquid crystal panel so that a prescribed chromaticity is attained based on the RGB output light levels detected by the detector.
