A display device includes: a substrate; a first bank including a first sub-bank and a second sub-bank spaced apart from each other on the substrate; a first electrode on the first sub-bank; a second electrode on the second sub-bank and spaced apart from the first electrode; and a light-emitting element between the first sub-bank and the second sub-bank. Each of the first and second sub-banks has a first area having a concave curved shape in a cross section and being adjacent to the light-emitting element. The first electrode has a first section extending beyond the first sub-bank toward the light-emitting element, the second electrode has a first section extending beyond the second sub-bank toward the light-emitting element, and a width of the first section of the first electrode is different from a width of the first section of the second electrode.
