Abstract: A display device includes a substrate including a plurality of pixel areas; and a pixel provided in each of the pixel areas. The pixel may include a first electrode and a second electrode extending in a first direction on the substrate and spaced from each other in a second direction different from the first direction; a bank pattern between the substrate and the first electrode and between the substrate and the second electrode, and including at least two sub-bank patterns in a same column and spaced from each other; and a plurality of light emitting elements between the first and second electrodes. Here, each of the first and second electrodes may have at least two or more widths in the second direction along the first direction.
