Abstract
A backlight device includes a plurality of light sources that emit light of different colors from each other, a plurality of color sensors that receive mixed-color light including light emitted from the light sources to detect light emission states of the light sources, a temperature sensor that measures a temperature in a proximity of the plurality of light sources, a brightness conversion unit that separates the mixed-color light to obtain a detection value for each of the light sources by converting values indicating the detected light emission states, and a calculation unit that corrects the obtained detection value by using information indicating a relationship between the measured temperature and a correction value, the calculation unit determining drive values for the light sources based on the corrected detection value.
