Abstract
According to one embodiment, a display device includes a substrate, a circuit layer including a metal-made feed line in a surrounding area, an insulating layer covering the circuit layer, a lower electrode, a rib, a partition above the rib, an upper electrode connected to the partition, an organic layer between the electrodes and a conductive layer connected to the partition. The partition and the conductive layer each includes a metal-made lower portion and an upper portion protruding from a side surface of the lower portion. The lower portion of the conductive layer and the feed line are in contact with each other in the first contact portion in the surrounding area.
