A display device includes a substrate, a first electrode, a second electrode, and a protective layer. The first electrode is disposed on the substrate. The second electrode has a first segment and a second segment. The first segment is located at a first side of the first electrode. The second segment is located at a second side of the first electrode. The second side is opposite to the first side. The protective layer overlaps the first segment and the second segment. The first segment has a length which is shorter than that of the second segment. The display device further includes a light-emitting element disposed on the substrate.
