ABSTRACT:
Disclosed is an LCD device including an electromagnetic wave shielding member for shielding the electromagnetic waves generated from electric power applied to lamp of backlight assembly. The shielding member comprising conductive material is coated on surface of a diffusing plate to have mesh shape. The shielding member is filled into groove formed on the surface of the diffusing plate to have mesh shape. Accordingly, the electromagnetic waves may be shielded from the LCD panel. Furthermore, the shielding member makes electrical contact with the chassis of the LCD device through various ground members so as to be connected to an earth potential, thereby being stabilized electrically. Accordingly, display quality of the LCD device is improved. A conductive tape is used as the ground member, and the conductive tape is strongly fixed to the chassis of the LCD device by means of conductive fixing clip or conductive screw.
