Abstract:
1. A liquid crystal display device comprising: a liquid crystal panel on which an image is formed; a light emitting diode (LED) unit to irradiate a backlight to the liquid crystal panel; a chassis in which the liquid crystal panel and the LED unit are installed; a LED circuit board including an LED chip that is installed to electrically contact the chassis and to control the LED unit; and a main circuit board connected to the liquid crystal panel and to the LED circuit board, wherein a grounding line connected to the main circuit board is formed on the LED circuit board and is spaced apart from the LED chip, wherein the LED circuit board comprises a base, the grounding line formed on a first surface of the base, a LED wiring formed on the first surface of the base and forms a signal path of the LED chip, a cover lay layer covering the LED wiring, and an LED pin and a grounding pin that are respectively formed at an end portion of the LED wiring and an end portion of the grounding line so as to be connected to the main circuit board, wherein another grounding line is further formed entirely on a second surface of the base and is connected to the grounding line formed on the first surface of the base via a via-hole.
