Backlight assembly and liquid crystal display device using the same

A backlight assembly comprising:

• a lamp assembly including a plurality of lamps, arranged in parallel, to generate a light, a power voltage being applied to the lamps through the lamp assembly;
• a receiving container to receive the lamp assembly, the receiving container including a bottom face and side faces;
• a plurality of sensors, disposed in the receiving container, to detect an operation state of the lamps and to output a plurality of sensing signals, one of the sensors facing a respective lamp;
• an inverter including i) a lamp driving module, disposed outside the receiving container, to provide the lamps with the power voltage, ii) voltage cut-off module comparing the sensing signals with a predetermined reference signal, the voltage cut-off module providing the lamp driving module with a voltage cut-off signal to prevent the lamp driving module from providing the lamps with the power voltage when at least one of the sensing signals has an amplitude smaller than the reference signal.
