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.

Abstract: A display device includes a substrate, pixels on the substrate, pads, and test lines. The pads are between the pixels and an edge of the substrate and include a first pad and a second pad. The test lines include a first test line and a second test line. The first test line includes a first section and a second section. The second section is closer to the edge of the substrate than the first section and is connected through the first section to the first pad. The second test line includes a first segment and a second segment. The second segment is closer to the edge of the substrate than the first segment and is connected through the first segment to the second pad. A minimum distance between the first section and the first segment is larger than a minimum distance between the second section and the second segment.
