A resistive element (115) is connected in series to a cathode terminal of an LED light source at a last stage (or an anode terminal of an LED light source at a first stage) of an LED chain (116), and the resistive element (115) is configured to be variable in resistance value in accordance with a variation of voltage drops of the LEDs connected in series so that a resistive element connected to an LED chain having a large voltage drop has a small resistance value while a resistive element connected to an LED chain having a small voltage drop has a large resistance value. With this configuration, the power, which has been wasted otherwise as heat in the backlight driver IC, may be dispersed to the resistive elements.
