Display device

1. 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.

2. The display device of claim 1 , wherein

the first contact portion is located between an end portion of the insulating layer and the end portion of the substrate in plan view.

3. The display device of claim 1 , wherein

the first contact portion surrounds the display area.

4. The display device of claim 1 , further comprising a relay wiring line connected to the feed line in a second contact portion located in the surrounding area and connected to the conductive layer in a third contact portion located in the surrounding area.

5. The display device of claim 4 , wherein

the second contact portion is located between the display area and the first contact portion in plan view.

6. The display device of claim 4 , wherein

the third contact portion is located between the display area and the second contact portion in plan view.

7. The display device of claim 4 , wherein

the relay wiring line is covered by the rib,

the third contact portion includes a plurality of contact holes provided in the rib, and
