A method for manufacturing a display device is provided. The method includes forming a circuit part; forming a planarization insulating layer on the circuit part; forming a separator in an area outside a display area in which a plurality of light emitting elements are formed by removing the planarization insulating layer at a position surrounding the display area; forming an electrically-conductive layer including a plurality of first electrodes and an auxiliary interconnect on the planarization insulating layer; forming an aperture-defining insulating layer that insulates the first electrodes from each other and has an aperture through which part of the first electrode is exposed; and forming a plurality of light emitting elements by stacking the first electrode, an organic layer, and a second electrode common to the plurality of light emitting elements.
