A backlight driving apparatus of an LCD device is provided to be capable of selectively changing a specific element of the backlight unit. A backlight driving apparatus of an LCD device comprises a switching circuit unit(64), a transformer(66), and a switching driving unit. The switching circuit unit changes and outputs the direct current voltage to the alternating current voltage. The transformer boosts the output voltage of the switching circuit, changes the voltage to the sinusoidal wave, and supplies it to the back light. The switch driving unit operates the switching circuit unit. Those elements such as the switching driving unit, the transformer, and the elements in the switching driving unit are selectively attachable/detachable to the substrate. |
