Circuit board and optical module, back light assembly having the circuit board and display device having the back light assembly

A circuit board, an optical module, a backlight assembly and a display apparatus having the same are disclosed having the same. Display device is isolated with a conductive pattern is connected to terminals formed on the surface first body, a is formed on the remaining portion other than the first heat sink, the connection of the second surface terminals formed on a second surface opposite the first surface, a portion at least 1 and the projections accommodating the optical module, a light emitting diode comprising a light emitting diode coupled to the circuit board and connection terminals including a protruding second heat sink is disposed the circuit to the storage container and the storage container for holding a substrate, a light emitting diode a light and a display panel to change the image of the light containing the information generated in the. Thus, the red, prevent the green and blue light-emitting diode using which the light-producing efficiency of the LED by rapidly passing through the air heat generated from during the LED forming the white light low, and thereby further improve the display quality of the image .
