Abstract: Provided is a display device that is capable of preventing heat generated in a plurality of light emitting diodes (LEDs) from being excessively transferred to a top chassis so that the occurrence of a safety accident and poor quality of a display panel can be prevented. The display device includes: a display panel on which an image is formed; a top chassis in front of the display panel and having an opening through which the display panel is exposed; a plurality of LEDs that provide light to the display panel; a printed circuit board (PCB) on which the plurality of LEDs are mounted; and a bottom chassis behind the PCB, wherein the PCB and the bottom chassis are arranged such that an air gap is between the PCB and an inner side surface of the bottom chassis.
