BACK LIGHT UNIT AND DISPLAY DEVICE HAVING THE SAME

摘要

PURPOSE: A backlight unit and a display device are provided to equip a heat emitting sheet in a lower part of a bottom chassis, thereby efficiently dispersing heat of an LED(Light Emitting Diode). CONSTITUTION: A backlight unit is separately arranged to a back side of a display panel(10). A middle mold(40a) supports the display panel and the backlight unit to be mutually separated. Heat emitting sheets(81,82) are arranged between a bottom chassis(70) and the backlight unit. A light guide plate(50) is located in a lower part of an optical sheet(30). A reflective sheet(55) is connected to a lower side of the light guide plate. A plurality of LEDs is mounted on PCBs(Printed Circuit Board)(60a,62a).
