A backlight unit (BLU) capable of stably driving various light source modules, and a display apparatus using the same are provided. A display apparatus includes a display and a BLU. The BLU includes a light source module, a converter, a light source driving unit which drives the light source module using the output voltage of the converter, and a control unit which controls the output voltage of the converter based on the output voltage of the light source driving unit. Therefore, the ratio of the input voltage to the output voltage of the light source driving element may be maintained uniformly for various light source modules, so the light source modules can be stably driven.
