    Abstract: A display device includes: a pixel circuit layer including a base layer, a pixel circuit, and a passivation layer including a well area and a protrusion area; and a light-emitting-element layer disposed on the pixel circuit layer, and including a light emitting element, and a connecting electrode, the light emitting element including a first electrode, a second electrode, and an emission part. The connecting electrode is disposed in the protrusion area, and at least a portion of the connecting electrode overlaps the well area and does not contact the passivation layer. The emission part includes a hole layer, an electron layer, and an emission layer. The hole layer connects the first electrode and the emission layer. The electron layer connects the second electrode and the emission layer. Each of the hole layer and the second electrode has an end portion on the connecting electrode.

    Abstract: A display device may include a first electrode, a second electrode, an emission layer, an intervening layer, and a first encapsulation layer. The second electrode may overlap the first electrode. The emission layer may be disposed between the first electrode and the second electrode, may overlap the first electrode, and may include a light emitting material. The intervening layer may directly contact the second electrode, may be spaced from each of the first electrode and the emission layer, and may include a fluorine compound. A first section of the first encapsulation layer may overlap the emission layer. The intervening layer may be positioned between the second electrode and a second section of the first encapsulation layer.

    Abstract: A donor substrate includes a base substrate; a light reflection layer on the base substrate and partially overlapping the base substrate; a light-to-heat conversion layer on the base substrate, and including a combination layer including an insulating material and a first metal material; and a transfer layer on the light-to-heat conversion layer. A ratio of the first metal material in the combination layer to the insulating material in the combination layer increases as a distance from the base substrate increases along a thickness direction of the light-to-heat conversion layer.

    Abstract: A display device includes a substrate; an auxiliary electrode including metal layers stacked in an undercut structure; and a light-emitting element layer. The light-emitting element layer includes a second common layer; and a common electrode which extend to the non-emission area. A side surface of the auxiliary electrode includes a first bonding portion in contact with the second common layer, and a second bonding portion in contact with the common electrode. The auxiliary electrode includes a first side and a second side facing each other in one direction, and a third side and a fourth side facing each other in other direction crossing the one direction. The first bonding portion has a first width at a first point of the first side and has a second width smaller than the first width at a second point of the third side.
