An Electro Magnetic Interference (EMI) shielding device ( 20 ) includes a body ( 201 ), at least a first engaging portion ( 203 ) extending from the body, and a pair of second engaging portions ( 205 ) formed on the body. A liquid crystal display device adopting the above mentioned EMI shielding device includes a TFT LCD panel, a power supply ( 12 ), an inverter ( 14 ) and an interface board ( 13 ). The power supply, the inverter and the interface board are formed on a printed circuit board ( 10 ). The EMI shielding device is positioned between the power supply and the inverter, with the first engaging portion inserted into the printed circuit board and the second engaging portions engaging with the printed circuit board. The EMI shielding device can reduce or potentially avoid the occurrence of EMI that would otherwise be produced by the printed circuit board.
