Abstract
A display device includes a first electrode and a second electrode disposed on a substrate; a first insulating layer disposed over the first electrode and the second electrode; a first bank and a second bank disposed on the first insulating layer and spaced apart from each other; and a light emitting element disposed between the first bank and the second bank. A top surface of the first bank may include a concave groove including a dam structure protruding in a first direction.
