According to one embodiment, a display device includes a first base electrode, a rib, a partition including a lower portion and an upper portion, a first lower electrode electrically connected to the first base electrode, a first organic layer, and a first upper electrode. The rib includes a first rib layer covering a peripheral portion of the first base electrode, and a second rib layer. A peripheral portion of the first lower electrode is located on the first rib layer. The lower portion and the first rib layer protrude from a side surface of the second rib layer. A width of the lower portion is less than a width of the first rib layer.
