1. A display device comprising:
a base layer comprising a display area and a non-display area; and
a plurality of pixels in the display area, each pixel of the plurality of pixels comprising a plurality of sub-pixels,
wherein each sub-pixel of the plurality of sub-pixels comprises a pixel circuit layer, and a display element layer, the display element layer comprising an emission area to emit light, and a non-emission area around a perimeter of the emission area,
wherein the display element layer further comprises:
a partition wall in the emission area of each sub-pixel;
a bank in the non-emission area of each sub-pixel, the bank being on the same surface as the partition wall;
a first electrode and a second electrode on the partition wall and spaced apart from each other; and
at least one light emitting element to emit the light, the at least one light emitting element extending in a longitudinal direction and being between the first and the second electrodes in the emission area of each sub-pixel,
wherein the partition wall comprises a partition wall portion extending in an extension direction different from the longitudinal direction such that the partition wall portion is overlapped with an interior of the sub-pixel,
wherein the partition wall and the bank are in direct contact with each other, and
wherein at least one partition wall is between light emitting elements that are adjacent to each other in the longitudinal direction within each sub-pixel.
