Abstract: A display device comprises conductive layers disposed on a substrate in different layers, a via layer on the conductive layers, a bank disposed on the via layer and defining a light emission area, bank patterns on the via layer and extended in a first direction, a first electrode on the bank patterns and extended in the first direction, and a second electrode disposed on the bank patterns and extended in the first direction, and light emitting elements on the first electrode and the second electrode. The bank patterns are spaced apart from each other. The first and second electrodes are spaced apart from each other. The bank and the bank patterns define an alignment area in which the light emitting elements are disposed. An area, in which two or more of the conductive layers overlap each other in a plan view is about 80% or more in the alignment area.
