Abstract: A display device includes a first electrode and a second electrode spaced apart from each other on a substrate, a light-emitting element disposed between the first electrode and the second electrode on the substrate, a third electrode disposed on the first electrode and an end of the light-emitting element, a fourth electrode disposed on the second electrode and another end of the light-emitting element, a first insulation pattern disposed on the third electrode, and a second insulation pattern disposed on the first insulation pattern. An end of the first insulation pattern corresponding to the end of the light-emitting element protrudes toward the another end of the light-emitting element further than an end of the third electrode, and the second insulation pattern fills a space adjacent to the end of the third electrode and formed under the first insulation pattern.

Abstract: A display device may include a substrate, and a display element layer disposed on the substrate and including a light emitting element that emits light in a display direction. The display element layer may include a first contact electrode electrically connected to the light emitting element, a second contact electrode electrically connected to the light emitting element, and a bank pattern having a shape extending in the display direction. At least one of the first contact electrode, the second contact electrode, and the bank pattern may include a transparent conductive polymer.
