1. A display device comprising:
a substrate including an active area having a plurality of pixels and a non-active area disposed on a periphery of the active area and including a pad region;
a pad electrode disposed in the pad region and including a first pad electrode and a second pad electrode disposed on the first pad electrode; and
a first insulating pattern interposed between an upper surface of the first pad electrode and the second pad electrode,
wherein, when viewed in a plan view, an entirety of 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 protrudes from the substrate in the thickness direction,
the second pad electrode directly contacts a portion of the upper surface of the first pad electrode that the first insulating pattern is not disposed on, and
when viewed in a plan view, an area of the second pad electrode is greater than an area of the first pad electrode.
