Zusammenfassung:	A backlight source of a LCD device includes constant-power red, green and blue LEDs emitting light having a constant output power, and a tone-correction red LED emitting light having a controlled output power controlled based on the temperature of the backlight source. The tone-correction red LED has a larger output power upon a temperature rise to supplement the reduced output power of the constant-power red LED.
