Abstract: A display device includes a substrate including a display area and a non-display area around the display area; and a display element layer on the substrate. The display element layer may include first and second electrodes extending in a first direction and spaced apart from each other in a second direction that is different from the first direction; a first light emitting element electrically coupled to the first and second electrodes; a first dummy electrode extending in the first direction and spaced apart from the first and second electrodes; second dummy electrodes spaced apart from each other in the first direction and spaced apart from the first electrode, the second electrode, and the first dummy electrode; and a second light emitting element electrically coupled to the first dummy electrode and the second dummy electrodes.

Abstract: A display device includes a first display substrate and a second display substrate. The first display substrate includes a first base, a first electrode disposed on the first base, a second electrode spaced apart from the first electrode, and a light emitting element disposed between the first electrode and the second electrode. The second display substrate faces the first display substrate and is configured to receive light emitted from the light emitting element. The second display substrate includes a second base, a first color filter disposed on a surface of the second base, and a first wavelength conversion pattern disposed on the first color filter. The first wavelength conversion pattern includes a first surface facing the first display substrate, and a second surface facing the first surface and the first color filter. The first surface includes a curved surface portion recessed toward the second surface.
