Abstract
According to one embodiment, a display device includes a substrate, an insulating layer, a lower electrode, a rib including an aperture and covering a periphery of the lower electrode, a partition above the rib, an upper electrode being in contact with the partition, and an organic layer between the electrodes. The organic layer includes a first organic layer that is in contact with the lower electrode through the aperture, and a second organic layer on the partition. At least a part of the periphery of the lower electrode is located between the insulating layer and the partition in a thickness direction of the insulating layer.

A display device comprising:
- a substrate;
- an insulating layer arranged above the substrate;
- a lower electrode arranged above the insulating layer;
- a rib formed of an inorganic material, including an aperture which overlaps with the lower electrode, and covering a periphery of the lower electrode;
- a partition arranged above the rib;
- an upper electrode opposed to the lower electrode and being in contact with the partition;
- and
- an organic layer located between the lower electrode and the upper electrode to emit light in accordance with a potential difference between the lower electrode and the upper electrode,
- the organic layer being in contact with the lower electrode through the aperture,
- the partition including a lower portion arranged on the rib, and an upper portion which is arranged on the lower portion, and which includes an end part protruding from a side surface of the lower portion,
- the rib, the lower portion of the partition, and the upper portion of the partition being stacked in a third direction, and
- at least a part of the periphery of the lower electrode being located between the insulating layer and the lower portion of the partition in the third direction.
A display device comprising:
- a substrate;
- an insulating layer arranged above the substrate;
- a first lower electrode and a second lower electrode arranged in a second direction above the insulating layer;
- a rib formed of an inorganic insulating material, the rib including a first aperture overlapping the first lower electrode and a second aperture overlapping the second lower electrode, and the rib covering a periphery of the first lower electrode and a periphery of the second lower electrode;
- a partition including a lower portion located on the rib and an upper portion located on the lower portion and including an end part protruding from a side surface of the lower portion;
- a first upper electrode opposed to the first lower electrode and a second upper electrode opposed to the second lower electrode, the first upper electrode and the second upper electrode being in contact with the lower portion of the partition;
- a first organic layer located between the first lower electrode and the first upper electrode to emit light in accordance with a potential difference between the first lower electrode and the first upper electrode;
- and
- a second organic layer located between the second lower electrode and the second upper electrode to emit light in accordance with a potential difference between the second lower electrode and the second upper electrode,
- wherein
- the rib, the lower portion of the partition, and the upper portion of the partition are stacked in a third direction crossing the second direction, and
- at least a part of the periphery of the first lower electrode and at least a part of the periphery of the second lower electrode are located between the insulating layer and the lower portion of the partition in the third direction.
