PURPOSE: A measurement device of a current for a backlight unit is provided to accurately measure current automatically flowing a light source array. CONSTITUTION: A current measuring device(IMB) comprises an input connector(IC), an output connector(OC), resistors](R1-R16), an input voltage selector(MUX I), an output voltage selector(MUX O), and a data processor(MCU). The input connector has input pins. . An output connector has output pins corresponding to the n input pins. The resistors connect the input pins to the out pins one by one. An input voltage selection part receives n input voltages from one side of the resistor and selects one of n input voltages according to the logic of a selection signal. An output voltage selection part receives n input voltages from the other side of the resistor and selects one of n output voltages according to the logic of a selection signal.
