Abstract: A display device includes pixels disposed in a display area and including first and second pixels that are adjacent to each other in a first direction, and a first integrated bank pattern disposed between the first and second pixels. Each of the pixels includes a first electrode and a second electrode that are spaced apart from each other along the first direction in a light emitting area and extend in a second direction, a first bank pattern portion overlapping the first electrode, and a second bank pattern portion overlapping the second electrode. The first integrated bank pattern includes a second bank pattern portion disposed at the first pixel, a first bank pattern portion disposed at the second pixel, and a protrusion extending in the second direction in a boundary area between the first pixel and the second pixel.

Abstract: A display device may include a pixel. The pixel may include: an emission area, a non-emission area, and a split area spaced from the emission area with the non-emission area interposed therebetween; a first pattern and a second pattern spaced from each other in a first direction, and each extending in a second direction; a first light emitting element aligned between the first and second patterns; a first electrode connected to a first end of the first light emitting element; a second electrode connected to a second end of the first light emitting element; a bank located in the non-emission area and defining the emission area and the split area; and an insulating pattern located between the first and second electrodes and overlapping the first light emitting element. Only two of the first pattern, the bank, and the insulating pattern may overlap each other.
