1. A display device comprising:
- a liquid crystal panel; and
a back light adjacent to the liquid crystal panel, the back light comprising;
a thermal conductor;
a first board over the thermal conductor;
a second board over the thermal conductor;
a first light-emitting diode over the first board;
a second light-emitting diode over the second board; and
a reflecting portion over the thermal conductor and between the first light-emitting diode and the second light-emitting diode,wherein the first board and the second board do not overlap with each other,wherein the first light-emitting diode does not overlap with the reflecting portion, andwherein the second light-emitting diode does not overlap with the reflecting portion.

Abstract
A cooling device is provided, where an LED backlight can be efficiently cooled in order to suppress display unevenness caused by heat generated from the LED backlight. In addition, a display device including the cooling device is also provided. A display device is provided, where the LED backlight can be cooled by arranging a coolant pipe on a back surface side of the LED backlight and supplying a coolant to a coolant pipe. Further, a display device is provided, where cooling efficiency of the LED backlight can be more improved by arranging a thermal conductor between the LED backlight and the cooling device.
