A display device is provided to separate a control printed circuit board from a bottom plane of a backlight assembly and make the lowest layer of the control printed circuit board of a metal material interrupting electromagnetic waves to protect the control printed circuit board from dust, thereby preventing erroneous operation of circuit devices formed on the control printed circuit board. Driving printed circuit boards(41,42) provide driving signals for displaying an image on a display panel(50). A backlight assembly(70) is formed under the display panel and generates lights for displaying the image through a plurality of light sources(71) installed inside. A control printed circuit board(49) has a plurality of layers and is formed under the backlight assembly to control the driving printed circuit boards. The control printed circuit board has a plurality of circuit devices and includes a first layer opposite to a bottom plane of the backlight assembly and a second layer made of a metal material combined with the first layer for interrupting electromagnetic waves. |
