A back light unit provides light to a light emission surface of a liquid crystal display device. The back light includes a plurality of lamps, a plurality of inverters, a plurality of first power lines, and a plurality of second power lines. Each lamp has first and second ends and is disposed substantially only in one of an integer (n) number regions of the light emission surface wherein the regions divide a length of the light emission surface into n regions. Each one of the first power lines are respectively connected to the first ends of the lamps and first connectors of the inverters, and each one of the second power lines are respectively connected to the second ends of the lamps and second connectors of the inverters.
