According to one embodiment, a display device includes a base electrode, a rib including an aperture overlapping the base electrode, a lower electrode disposed at the aperture and electrically connected to the base electrode, a partition including a lower part disposed on the rib and an upper part projecting from a side surface of the lower part, a organic layer covering the lower electrode, and a upper electrode disposed on the organic layer. A periphery of the base electrode is covered by the rib. The base electrode is formed of a first metal material. A periphery of the lower electrode is located on the rib. The lower electrode is formed of a second metal material different from the first metal material.
