Display device

A display device comprising:

• a substrate;
• a pixel circuit overlapping the substrate;
• an insulating layer on the pixel circuit and including a contact hole;
• a first lower electrode and a second lower electrode on the insulating layer and arranged in a second direction crossing at a right angle to a third direction normal to an upper surface of the substrate;
• a first upper electrode opposing the first lower electrode in the third direction;
• a second upper electrode opposing the second lower electrode in the third direction;
• a first organic layer located between the first lower electrode and the first upper electrode and including a first light-emitting layer;
• a second organic layer located between the second lower electrode and the second upper electrode and including a second light-emitting layer;
• a rib formed of a first inorganic material on the first lower electrode and the second lower electrode and including:
• a first pixel aperture overlapping the first lower electrode in a plan view, and
• a second pixel aperture overlapping the second lower electrode in the plan view;
• a partition located between the first pixel aperture and the second pixel aperture in the plan view, a thickness of the rib being less than a thickness of the partition, and the partition including a lower portion on the rib, and
• an upper portion on the lower portion and extending beyond a side surface of the lower portion in the second direction, wherein
• the first light-emitting layer emits a light of a first color,
• the second light-emitting layer emits a light of a second color different from the first color,
• the contact hole includes a contact area where the first lower electrode is in electrical contact with the pixel circuit,
• the lower portion of the partition overlaps an entirety of the contact area of the contact hole,
• the rib includes:
• a lower surface in direct contact with the first lower electrode and the second lower electrode,
• an upper surface opposing the lower surface, the upper surface being further from the substrate compared to the lower surface in the third direction and including a first portion and a second portion, and
• a side surface connecting the lower surface to the upper surface,
• no part of the upper surface of the rib is in direct contact with the first lower electrode and no part of the upper surface of the rib is in direct contact with the second lower electrode,
• the second portion of the upper surface of the rib is closer to the substrate compared to the first portion of the upper surface of the rib in the third direction, and
• the second portion of the upper surface of the rib overlaps the contact area of the contact hole in the third direction.
