Abstract: A display device includes a plurality of sub-pixels disposed on a display area of the display device and including a first electrode, a light emitting layer, and a second electrode, a pixel-defining layer defining emission areas of the plurality of sub-pixels, respectively, an organic planarization layer disposed on the pixel-defining layer and comprising one or more valleys overlapping a first area in a plan view and at least one protrusion overlapping a second area in a plan view, and a high-refractive planarization layer disposed on the organic planarization layer. The first area is located at an edge of the display area. A second area is located in a non-display area of the display device.

Abstract: A display device includes a first electrode and a second electrode disposed on a substrate and spaced part from each other in a first direction. A light emitting element is disposed between the first electrode and the second electrode. A third electrode is disposed on the first electrode and electrically contacts an end portion of the light emitting element. A fourth electrode is disposed on the second electrode and electrically contacts another end portion of the light emitting element. A side of the third electrode and a side of the first electrode are located on a first virtual line substantially perpendicular to the substrate. A side of the fourth electrode facing the side of the third electrode and the side of the second electrode are located on a second virtual line substantially perpendicular to the substrate.

Abstract: A display device includes: a display area and a non-display area; anode electrodes in the display area; an inorganic insulating layer on the anode electrodes; a bank structure on the inorganic insulating layer, and including openings overlapping with the anode electrodes; light emitting layers on the anode electrodes and in the openings; cathode electrodes on the light emitting layers and in the openings; a first power line in the non-display area; and a power connection electrode including through portions partially overlapping with the first power line, and between the first power line and the display area. The bank structure includes: hole patterns on the power connection electrode in the non-display area, and overlapping with the through portions; a first bank layer; and a second bank layer on the first bank layer. The second bank layer includes a tip protruding from a sidewall of the first bank layer.
