Abstract
According to one embodiment, a display device includes a lower electrode, a rib, a partition including a lower portion which is provided on the rib and is formed of a conductive material, and an upper portion which is provided on the lower portion and protrudes from a side surface of the lower portion, an organic layer provided on the lower electrode, an upper electrode which covers the organic layer and is in contact with the lower portion of the partition, a sealing layer which covers the upper electrode, and a common sealing layer formed of an inorganic insulating material and provided over a broader range than the sealing layer above the sealing layer. The sealing layer is formed of silicon nitride or a transparent oxide.
