A display device includes a display panel including a plurality of pad electrodes, a driving member attached to the display panel and including a plurality of bumps facing the plurality of pad electrodes, respectively, a plurality of conductive particles interposed between the display panel and the driving member, and a plurality of alignment electrodes separated from the plurality of pad electrodes and the plurality of bumps, where an opening is defined in at least one of a pad electrode of the plurality of pad electrodes and a bump of the plurality of bumps includes an opening, and an alignment electrode of the plurality of alignment electrodes is disposed in the opening.

Display device and method of manufacturing the same

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.
