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.
