  • Publication number: 20180011369
    Abstract: A display device includes a pad portion disposed on a first substrate, a connection member disposed on the pad portion, and an anisotropic conductive layer disposed between the pad portion and the connection member, the anisotropic conductive layer including conductive particles. The pad portion includes a pad, the pad including a first pad electrode and a second pad electrode. A first insulating layer is disposed between the first pad electrode and the second pad electrode. The first insulating layer overlaps the first pad electrode. The second pad electrode is connected to the first pad electrode through a first contact hole. The first contact hole overlaps a center of the first pad electrode. The first pad electrode is at least twice as wide as the first contact hole.
