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.

A display device comprising:
- a substrate;
- a circuit layer including a pixel circuit disposed in a display area containing pixels, and a metal-made feed line disposed in a surrounding area between an end portion of the substrate and the display area;
- an insulating layer covering the circuit layer;
- a lower electrode disposed above the insulating layer in the display area, to which voltage is supplied from the pixel circuit;
- a rib including an aperture overlapping the lower electrode;
- a partition disposed above the rib in the display area;
- an upper electrode opposing the lower electrode and connected to the partition;
- an organic layer disposed between the lower electrode and the upper electrode and emitting light in response to a potential difference between the lower electrode and the upper electrode;
- and
- a conductive layer disposed in the surrounding area and connected to the partition,
- wherein
- 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, and
- the lower portion of the conductive layer and the feed line are in contact with each other in the first contact portion located in the surrounding area.
