Abstract: A display device includes a substrate including an active area having pixels and a non-active area including a pad region. A pad electrode is disposed in the pad region and includes a first pad electrode and a second pad electrode disposed on the first pad electrode. A first insulating pattern is interposed between the first and second pad electrodes. In a plan view, the first insulating pattern is positioned inside the first pad electrode, and a portion of the second pad electrode overlapping the first insulating pattern protrudes further from the substrate in a thickness direction than a portion of the second pad electrode not overlapping the first insulating pattern. The second pad electrode directly contacts a portion of the upper surface of the first pad electrode. In a plan view, an area of the second pad electrode is greater than an area of the first pad electrode.
