Abstract

According to one embodiment, a display device includes a base, a lower electrode disposed in a first region on the base, a rib covering a part of the lower electrode and including an aperture overlapping the first region, a partition including a lower portion disposed on the rib and an upper portion protruding from a side surface of the lower portion, which compartmentalizes the first region and a second region different from the first region, an organic layer disposed in the first region and in contact with the lower electrode via the aperture and an upper electrode disposed on the organic layer, and the organic layer and the upper electrode are not disposed in the second region.

Claims (26)

1 . A display device comprising:

a base;

a lower electrode disposed in a first region on the base;

a rib covering a part of the lower electrode and including an aperture overlapping the first region;
