摘要： A display device may include a substrate including pixels; a first bank that defines an emission area of the pixels; a first electrode and a second electrode spaced apart from each other in the emission area; a first insulating layer disposed on the first electrode and the second electrode; light emitting elements disposed on the first insulating layer between the first electrode and the second electrode; a second insulating layer disposed on the first bank; a first opening passing through the first insulating layer; and a second opening passing through the second insulating layer. The first opening and the second opening may overlap the first bank.

摘要： A display device according to an embodiment of the present disclosure may include pixels including a first pixel and a second pixel sequentially arranged in a display area along a first direction, each of the first pixel and the second pixel including sub pixels arranged along a second direction corresponding to emission areas, and a first power line and a second power line connected to the pixels. Each of the sub pixels may include a light emitting element, a first electrode connected between the light emitting element and the first power line, and a second electrode connected between the light emitting element and the second power line. The second electrodes of the sub pixels of the first and second pixels may be integrally connected to each other to configure an integrated electrode, and may be commonly connected to the second power line through a first contact portion.
