Abstract: A display device includes: a display panel having a display region in which a pixel is disposed and a non-display region in which a pad electrode is disposed; a driving part disposed on the display panel and having a bump electrode disposed to correspond to the pad electrode; and an adhesive layer in contact with the pad electrode and the bump electrode. The pad electrode includes: a first connection pattern containing a conductive material; an auxiliary pattern disposed on the first connection pattern, protruding toward the bump electrode, and containing an insulating material; and a second connection pattern, which contains a conductive material, of which a portion is disposed on the auxiliary pattern, and in which an opening that exposes a portion of the auxiliary pattern is defined, and the auxiliary pattern includes a tip portion more protruding toward the opening than the first connection pattern.

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.
