The present invention discloses a back-light module suitable in a liquid crystal display (LCD). The back-light module comprises a first-polarity-voltage output device, a second-polarity-voltage output device, and a lighting device. The first-polarity-voltage output device electrically connects to a first-polarity transformer in a first connecting structure to output a first-polarity-voltage. The second-polarity-voltage output device electrically connects to a second-polarity transformer in a second connecting structure to output a second-polarity-voltage. The lighting device comprises at least a lamp with a first-polarity end and a second-polarity end. The first-polarity end electrically connects to the first-polarity-voltage output device, and the second-polarity end electrically connects to the second-polarity-voltage output device.
