    Abstract: A display device may include: a base layer including a display area and a non-display area; and a plurality of pixels in the display area, and each including a plurality of sub-pixels each including an emission area configured to emit light and a peripheral area around the emission area. The sub-pixels may include: at least one first electrode and at least one second electrode extending in a direction and spaced apart from each other; and a plurality of light emitting elements between a first electrode of the at least one first electrode and a second electrode of the at least one second electrode and configured to emit light. At least one of the first electrode and the second electrode may include at least two first electrode patterns spaced apart from each other, and coupled by at least one first connection pattern in the emission area.
