Abstract

The present invention relates to a liquid crystal display device, in particular to an inverter circuit suitable for supplying power to a backlight, and a liquid crystal display device using the inverter circuit. A liquid crystal display device according to an embodiment of the present invention includes: a liquid crystal display panel; a plurality of lamps for irradiating light to the liquid crystal display panel; collectively drive the lamp; and a bottom cover for accommodating the lamp and disposed near the inverter circuit, and the printed circuit board includes a first surface on which the transformer is mounted and a second surface on the opposite side of the first surface and on the first surface Between the second surface and the second surface is an insulating base layer, and a metal shielding pattern is formed on the second surface, the metal shielding pattern overlaps with the transformer and shields the magnetic flux from the transformer to the bottom cover.

Description

[0001] This application claims priority from Korean Patent Application No. P06-0056120 filed on June 21, 2006, the entire contents of which are hereby incorporated by reference. technical field [0002] The present invention relates to a liquid crystal display device, in particular to an inverter circuit suitable for supplying power to a backlight and a liquid crystal display device using the inverter circuit. Background technique [0003] With the development of the information society, the demand for display devices for displaying images has increased in various forms, and various flat display devices such as LCD (Liquid Crystal Display), PDP (Plasma Display Panel), ELD (Electro Emissive Display), VFD (Vacuum Fluorescent Display), etc. [0004] Liquid crystal display devices among flat panel display devices have been widely used because they can be driven with low power and are excellent in image quality. [0005] In general, a liquid crystal display device uses an electr...
