ABSTRACT:
It is an object to manufacture a highly reliable backlight device with less color unevenness and less luminance unevenness, and a high-performance and highly reliable display device including the backlight device, which can display a high quality image. A light emitting diode (LED) is used as a light source of a backlight device and thermoelectric elements are provided in a chassis for holding the light emitting diode so as to surround the light emitting diode (the thermoelectric elements are provided under the light emitting diode and on the four sides thereof). A temperature in the backlight device is adjusted by cooling and heating by the thermoelectric elements.
