Abstract:
1. A liquid crystal display device, comprising: a liquid crystal display panel; a plurality of lamps for irradiating light onto the liquid crystal display panel; a cover bottom that houses the plurality of lamps; an inverter printed circuit board having a first surface and a second surface opposite to the first surface with an insulation base layer between the first and second surfaces, wherein the second surface is adjacent to the cover bottom; a transformer on the first surface of the inverter printed circuit board; and a metal shielding pattern for shielding magnetic flux of the transformer on the second surface of the inverter printed circuit board directly between the transformer and the cover bottom, a first metal pattern on the first surface in an area other than where the transformer is located, a second metal pattern on the second surface corresponding to the first metal pattern, wherein the metal shielding pattern is formed on the second surface corresponding to the transformer, and wherein the metal shielding pattern is electrically isolated from the second metal pattern.
