A backlight driving apparatus is disclosed which is capable of simplifying a circuit configuration for driving of a plurality of light emitting diode arrays and making the current balance of the light emitting diode arrays uniform. The backlight driving apparatus includes n light emitting diode arrays that include a plurality of light emitting diodes connected in series, a power source for generating a driving current, a current generator for generating currents to drive the light emitting diode arrays using the driving current, respectively, and a current mirror circuit for allowing substantially the same amount of currents to flow respectively through the light emitting diode arrays based on current from any one of the n light emitting diode arrays.
