  • Patent number: 9142602
    Abstract: A display device includes a substrate including a wiring portion, a pad unit provided on the substrate and extended from the wiring portion, an integrated circuit chip electrically connected to the pad unit and mounted on the substrate, and an anisotropic conductive film configured to electrically connect the pad unit and the integrated chip to each other. The anisotropic conductive film includes an adhesive layer provided between the pad unit and the integrated circuit chip and at least one conductive ball scattered in the adhesive layer. A heat generator is also provided on the substrate. The heat generator is configured to come into contact with the anisotropic conductive film to supply heat to the anisotropic conductive film.
