According to an exemplary embodiment of the present disclosure, a display device includes a display panel having a substrate, a back cover which supports the display panel on one surface of the display panel, a flexible film which is electrically connected to a pad unit of the display panel, a sealing layer which covers one ends of the pad unit and the flexible film and a dam which is disposed at an end of the display panel in which the flexible film is located and is in contact with a rear surface of the flexible film. Therefore, according to the present disclosure, the overflowing of the conductive adhesive layer at the end of the substrate is suppressed and the un-curing of the micro seal is suppressed to suppress the curling of the polyimide substrate and the tearing of the flexible film.
