Abstract
An LCD device in which a plurality of grounding protrusions are formed in a region not having a signal transmission pattern among the bottom surface of a printed circuit board in contact with a bottom chassis so as to increase a contact area between the printed circuit board and the bottom chassis, to thereby prevent a damage caused by an electromagnetic wave and error of devices.
