Abstract: A backlight assembly and an LCD using the same are provided to simplify the structure of the LCD and improve assemblability by optimizing a connection structure between the electrode terminal of lamp's end parts and an inverter PCB(Printed Circuit Board). A backlight assembly includes a bottom cover(110), plural lamps(120), and a common electrode(160). The bottom cover has a hole(111) formed in the lower side of the inside. The lamps are set in the inside of the bottom cover to supply light. The common electrode is joined in the inside of the bottom cover, connects end parts of the lamps, and has a fastening projection(164) projected to the outside of the bottom cover through the hole.

Abstract: 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.
