Abstract: A display device includes a display element layer on a substrate. The display element layer may include first and second electrodes, and light emitting elements electrically coupled to the first and second electrodes. The first electrode may include first protrusions, a first portion located between the first protrusions, a second portion corresponding to a side of each first protrusion, and a third portion coupled between the first portion and a first end of the second portion. The second electrode may include second protrusions that protrude toward the first electrode and are spaced apart from each other in the first direction, a first portion located between the second protrusions, a second portion corresponding to a side of each of the second protrusions, and a third portion coupled between the first portion and a first end of the second portion.
