An inverter and a liquid crystal display device having the same are provided to decrease heat generated at a transformer by forming a heat radiating unit on a printed circuit board to flow air by convection current. A liquid crystal display device includes a liquid crystal panel, at least one light emitting lamp, an inverter(110), and a printed circuit board(115). The at least one light emitting lamp supplies light to the liquid crystal panel. The inverter converts external voltage to supply the converted voltage to the light emitting lamp, and has at least one transformer(111). The printed circuit board mounts the inverter thereon, and has a heat radiating unit(120) at the lower part of the transformer. The light emitting lamp is selected from a group of a CCFL(Cold Cathode Fluorescent Lamp), an HCFL(Hot Cathode Fluorescence Lamp), an EL(Electro Luminescence) and an LED(Light Emitting Diode). |
