1. An organic light emitting element comprising:
a first electrode; a bump partially covering an end of the first electrode and having an island shape, which has a thickness larger than a thickness of the first electrode; an organic emission layer on the first electrode and the bump; and a second electrode on the organic emission layer, wherein the bump has a curved surface, and wherein the curved surface of the bump comprises: a first sub-curved surface contacting a surface of the first electrode and forming a first angle with the surface of the first electrode; and a second sub-curved surface that has a bend, extends from the first sub-curved surface, and forms a second angle with the surface of the first electrode that is larger than the first angle.
