A direct type backlight device includes a lower chassis, a reflective sheet disposed on a bottom portion of the lower chassis, and a plurality of light emitting diode (LED) bars disposed on an upper surface of the reflective sheet. Each of the plurality of LED bars includes a bar-shaped printed circuit board disposed on the upper surface of the reflective sheet, a plurality of LEDs disposed on an upper surface of the printed circuit board, and a reflective member provided on the upper surface of the printed circuit board. A reflectance of the reflective member is at least 90% of a reflectance of the reflective sheet.
