Abstract: A display device includes a display panel, a mold frame, and graphite sheets. The mold frame includes a mold slot portion therethrough to support the display panel. The graphite sheets include a central portion on a rear surface of the display panel, and end portions passing through the mold slot portion to be on the rear surface of the mold frame. The graphite sheet is rolled and arranged in a mounting space between the display panel and a back cover, such that heat generated from the display panel may be dissipated to the outside via the graphite sheet and the back cover.
