ABSTRACT:
A lamp driving device for driving a plurality of lamps in a liquid crystal display device and a liquid crystal display device using a lamp driving device are provided. The lamp driving device includes an inverter substrate, a plurality of transformers on the inverter substrate to supply a high voltage AC waveform to each of the lamps; and a plurality of pattern capacitors on the inverter substrate to limit the electric current supplied to each of the lamps. The patterns capacitors have a plurality of capacitor patterns on a front surface of the inverter substrate with a designated distance therebetween and a first ground line on a rear surface of the inverter substrate overlapping the capacitor patterns.
