Patent ID: 8389315

Claim:
A method for manufacturing a display device, the method comprising the steps of: forming a circuit part including a drive element over a substrate; 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 connected to the drive element 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 including a light emitting layer, and a second electrode common to the plurality of light emitting elements in that order over an exposed part of each of the plurality of first electrodes, wherein in the forming the electrically-conductive layer, the forming the aperture-defining insulating layer, and the forming the light emitting elements, the electrically-conductive layer, the aperture-defining insulating layer, and the plurality of light emitting elements are so formed that, in a whole area inside the separator, at least any of the electrically-conductive layer and the aperture-defining insulating layer intervenes between the planarization insulating layer and the second electrode and between the planarization insulating layer and the organic layer.
