摘要：
A direct-type backlight device for a non-self-luminous image display panel has a light-emitting area corresponding to a display area of the image display panel. The light-emitting area is arranged by combining a plurality of backlight substrates each of which is provided with (i) a color sensor for detecting an incident light intensity and (ii) red, green, and blue LEDs whose respective light intensities are controlled in accordance with a detection result obtained by the color sensor. This arrangement allows reduction of brightness unevenness entirely in the light-emitting area of the backlight device.
