Abstract: According to one embodiment, a manufacturing method of a display device includes forming a lower electrode, forming an insulating layer which covers the lower electrode, forming a partition which includes a lower portion located on the insulating layer and formed of a conductive material and an upper portion located on the lower portion and protruding from a side surface of the lower portion, forming an aperture which overlaps the lower electrode by patterning the insulating layer, forming an organic layer including a light emitting layer, on the lower electrode, and forming an upper electrode which covers the organic layer and is in contact with the lower portion of the partition. The insulating layer is formed of tetraethoxysilane (TEOS).

Abstract: According to one embodiment, a display device includes a lower electrode, a rib including an aperture overlapping the lower electrode, a partition on the rib, an upper electrode which is in contact with the partition, an organic layer between the lower electrode and the upper electrode, and a sealing layer above the upper electrode. The partition includes a lower portion provided on the rib, and an upper portion provided on the lower portion and including an end portion protruding from a side surface of the lower portion. The upper portion contains at least one of a conductive oxide and titanium.
