An apparatus for driving lamps and a liquid crystal display having the same, wherein the uniformity of luminance among lamps is improved, includes a main transformer unit for supplying a driving voltage to the lamps, and a balance transformer unit for making a lamp current of each of the lamps uniform. The balance transformer unit has a plurality of coils wound on a single body, and the coils have the same turns ratio and share magnetic flux so that a constant uniform current can flow through each of the coils. Accordingly, a lamp current of each of the lamps connected to the respective coils of the balance transformer unit can be maintained to be constant, and thus, the luminance of the lamp can be maintained uniformly.
