摘要： An inverter and an LCD(Liquid Crystal Display) using the same are provided to insert a magnetic flux shielding plate between a PCB(Printed Circuit Board) and a bottom case of an inverter, thereby intercepting the magnetic flux leaked from a transformer. A transformer(110) generates the driving voltage in order to drive a light source of a backlight unit. A PCB(120) applies the power supplied by the transformer to the light source. A magnetic flux shielding plate(150) is arranged between the PCB and a bottom case and shields the leakage magnetic flux generated at the transformer. The magnetic flux shielding plate is made of an aluminum alloy containing aluminum of above 90wt.%. The magnetic flux shielding plate is also made of non-magnetic materials. The magnetic flux shielding plate is also a non-magnetic metal. The magnetic flux shielding plate is a ferrite core plate. An insulating plate is additionally included between the PCB and the bottom case.
