Abstract:
A backlight unit includes a mold frame, a metal core printed circuit board (“MCPCB”) on which at least one light emitting diode (“LED”) is mounted, a reflector, a light guide plate, and an optical sheet. The mold frame includes an MCPCB fixing portion, the MCPCB is directly and removably disposed on the MCPCB fixing portion, and a lower surface of the MCPCB is exposed to the outside of the mold frame. On the MCPCB, a reflector, a light guide plate, and an optical sheet are placed in the order named. The light guide plate has a light entering surface facing the LED.
